1.1. Genera]-
The L90O0 is a versatile Gang and Set Eprom Programmer capable of programming vi-rtually aIl- current single raj-I EPROMs up to 4M bj-ts and beyond as new devices are j-ntroduced. New devices can be catered for by changing the programmer's eprom which takes about five minutes. Updates are produced by LLOYD RESEARCH on a monthly basis and are avail-abl-e from distributors. One or two socket modules can be fitted to cater for different requirements. For example, a PLCC module could be fitted at the same time as a DIL module. There are separate modules for 24/28/32 pin eproms and 40 pin devices. See device list for current devices and modules required.
The programmer has been designed for use in R&D, Production and Product support environments. Separate operating systems are used to prompt the user. In general, the producti-on mode is a subset of the R&D mode.
A11 programming operations are performed from ram. Master data can be loaded j-nto ram through one or more master devices or through the serial or paralIe1 ports. The latter is recommended because the transfer speed approaches 60,0OO baud.
The L9OOO features a separate data bus to each 32 pin socket with two buses being used for 40 pin sockets. It is, therefore, possible to program a set of eight different 24/28/32 pin eproms or four 40 pin eproms at the same time. This is ideal for set programming systems with 16 or 32 bit data.
The internal ram size can be expanded from 2M bits to 32M bits and beyond.
Each module has green and red leds. The red l-eds indicate that power has been applj-ed to the module and it is not, therefore, advisabl-e to fit or remove devices. The green leds are status lights for each socket. A permanently ilfuminated light indicates that a device has passed a test - program or blank check, etc. A flashj-ng light indicates that a device has failed a test. Lights are left on or flashing until the next function has been started.
The control-s are arranged in three separate groups on the top panel.
BASIC CONTROLS: This group of 10 buttons is mostly used for simple copying from the ram to the copy sockets. It also inc1udes f acil-ities to set the device type and the communications parameters .
2. RAM CONTROLS: This group of 5 buttons above the fi-rst group contains the main control-s for reading data into memory and manipulati-ng it. Subsequently, data can be transmitted to another computer system in a variety of formats.
3. EDITING CONTROLS& HEX KEYPAD: This group of 16 controls is used for hexadecimal editing. Some of these keys have a dual function for the more sophisticated editing functions. Groups 2 and 3 (and part of group 1) can be'locked' out so that there is l-j-ttle danger of an unskil-Ied operator damaging components by mistake.
These facj-Iities enabl-e the microprocessor engineer to perform many operations which woul-d otherwise need a development system.
The L900O can program a set of 2, 4 or B devices simul-taneously. If the data word length was B bj-ts, consecutive bl-ocks of data would be programmed j-nto successive devices. If the word length was 16 bits, even bytes would be programmed into one device and odd bytes into another device, etc.
For the editing operations, the master data must be read into memory through the RS232C port or the master socket.
New devices and facj-Iiti-es can be added by updating the programmer's eprom. This procedure is described in Section 13.
A smal-l- internal battery enabl-es the programmer to 'remember' the fast device type programmed and such details as the R5232 l-ine parameters. This saves setting up the instrument every time power is connected.
Section 3 of this manual- describes the outline purpose of each controf and Secti-on 4 describes the detailed operation.
CAUTION: Whil-st every precaution has been taken against accidentally damaging devices, damage may occur if the following precautions are not taken:
NEVER LEAVE DEVICES IN THE COPY SOCKETS WHEN THE INSTRUMENT IS TURNED ON OR OFF. ''LIVE'' NEVER ]NSERT OR REMOVE DEVICES WHEN THE RED WARNING LIGHT IS oN.
NEVER TURN THE PROGRAMMEROFF UNLESS IT IS IN THE INITIAL STATE Such action may cause the programmer to rforget' the parameters and passwords which are normally stored when power is disconnected.
The programmer can be returned to the initial state by pressing CANCEL. 2. INSTALLATION
2.7 . Supply vol-tage adi ustment and fuse reolacement
The programmer is supplied in two versions for use on different power supplies.
L9000 - 1. Nominal power supply l10V or L2OV 50/60 Hz. Fused at 2A. It is important to use anti- surge fuses.
L9000 2. Nomj-nal power supply 22OY or 24OV 50 / 60 Hz. Fused at 1A. It is i-mportant to use anti- surge fuses.
Voltages shoufd not vary by more than +BZ/ -B?. Power consumptj-on is about SOVA.
The supply voltage setting of each instrument is printed on the fuse section of the mains plug fitted at the back of the instrument. The appropriate voltage is sel-ected by withdrawing the fusehofder and inserting i-t with the correct voftage opposite the arrow. Note that the fuse must be fitted opposite the chosen mains voltage. If the programmer is being used on say 22OV and 24OV, two fuses must be fitted.
Note that the instrument may be fused with either a 2Omm or L.25" fuse. The correct fuse rating must always be used for replacement. 'c1ean' The programmer shoul-d be connected to a supply, free from high frequency noise and electrical transients which can, for example, be caused by motors starting and stopping.
The programmer is supplied with a mains lead which should be plugged into the rear mains IEC socket.
The mains l-ead wires are connected as foflows:
Brown Lj-ve Blue Neutral Green/YeIfow Earth
NEVER CONNECT THIS INSTRUMENT TO THE WRONGSUPPLY VOLTAGE. 2.2. How to switch on
The instrument may be turned on by the mains swj-tch fitted to the rear IEC maj-ns p1ug.
After a few seconds, the sign on message:
LLOYD RESEARCH LTD L90OO VH.SS ORM Ram
Where H is the hardware version to which this software applies, SS is the software version, RM is the ram size expressed in M bits.
2.3. The IN]TIAL state
Frequently these instructj-ons refer to the INITIAL state. This is the state to which the programmer returns at the end of each function regardless of what is shown on the display. The INITIAL state is automatically entered into whenever the CANCEL button is pressed.
2.4. Install-ing or changing modul-es
One or two modufes can be fitted to the L90OO. Any modufe can be install-ed j-n either position with any other modufe. However, it is not possible to program two different types of device at the same time ! Modules may be instal-l-ed when the power is on but eproms shoul-d not be in the sockets when modul-es are f itted or removed. It is important NOT to leave devices in copy sockets for one module whilst using the other module. A blank module is availabl-e.
To instal a module, the moduLe shoul-d be placed on the L9OOO so that its plug fj-ts the correspondj-ng socket on the L900O. The modu1e shoul-d be gently pressed into posi-ti-on until- resistance is feLt. A screwdriver should then be used to lock the modul-e to the base unit. Note there are two l-ock screws on each modul-e.
To remove a module, unscrew the lock screws and gently remove the module whifst being carefuf to keep the module hori-zontal. Do NOT Iift up the front of the module and feave the rear in position - you may break the connector. 3. THE CONTROLS
The control-s are arranged in three separate groups on the top panel. Each group has a specific function as described in Section 1 - INTRODUCTION.
Most of the basic functions can be used regardless of the state of the password. Ram and editing functions are protected by a password. The password is graded into levefs and only comes into operati-on when the l-evel- j-s exceeded ( see Appendix 1) .
Note that the L90OO keyboard is buffered. This enabfes the experJ-enced user to feed i-n a few extra commands whil-st the programmer is still executing an existing command. For example, it may be required to downtoad a fil-e and start programming. Normally the user woutd have to wai-t until- al-l- data had been downloaded before pressi-ng 'Program from ram'. With the buffered keyboard, the user can sJ-mply press 'Program from ram', 0 for ram start O, and ACCEPT. After downloadi^g, the L9O0O wil-l- pick up these commands and start programming.
These 10 control buttons are located on the right-hand side of the top panel. SET TYPE Sets the device type 27256, 27OLO, etc. Each press of the STEP > button selects the next devj-ce type. In order to reduce the number of presses, the process is split into two functions with the first sefection being the device size. PROGRAM Programs copy devj-ces from ram. The sequence FROM fol-l-owed is blank check or illegal bit test, RAM program and verify, and second verify. The copy socket light witl be illuminated after successfuf verificatj-on whereas a flashing light indicates a faulty device. VERIFY The copy devices are verified with ram. After WITH successful verificatj-on, the socket light is RAM j-l-l-uminated. A flashi-ng light i-ndicates that a device has not been successfulJ-y verified. BLANK Thj-s sequence checks that all- bits are set to FF- ERASE or 00 if appropriate. CHECK MASTER This function checks a single device by reading it twj-ce at high and l-ow Vcc. The Intelligent Identifier is read and the manufacturer and device codes are displayed. SET COMMS The RS232 line parameters and input/output port can be specified. STEP This button advances the function currently being selected. For example, if the current memory and address is xxxx, pressing STEP >, sel-ects address xxxx + 1. STEP STEP < selects xxxx - 1. For certain functions, STEP is al-so used to answer questions where corresponds to YES and < to NO. CANCEL Stops current operati-on. This button may be pressed safely at any time to end any sequence. This button is continuously monitored by the programmer. The programmer is automatically put into the INITIAL state. ACCEPT This button starts a sequence or accepts data. 3.2. Ram ControLs These five control-s are located above the basic controfs on the top panel. READ MASTER Reads the MASTER device(s) into ram. PROGRAM FROM This function enabfes devices to be programmed from one of the ports whil-st storing data in ram. VERIFY WITH This function compares data being downloaded PORT with data in ram. DOWNLOAD Thi-s function is used to read data i-nto the memory through the RS232C or Centronics interfaces. The RS232 li-ne parameters, such as baud rate, must have been previously selected by SET COMMS - see basic controls - if using the RS232 port. UPLOAD This function outputs a sel-ected portion of the memory contents to the RS232C or Centronics interface. The RS232 l-ine parameters must have been sefected by SET COMMS - see basic controls - if using the R5232 port. 3.3. Editing controls and hex keypad These are the 76 buttons arranged in a square at the left-hand side of the instrument. They may be used for altering memory contents using hexadecimal notation. When used for special editing functions, a particular number sel,ects a certain function. For example, 6 enabl-es the user to compute the checksum between two ram addresses. O Keyboard Lock: If the current password is known, the keyboard can be l-ocked. The password and/or the password l-evel can be changed. Edits the contents of the current memory address using hexadecimal- notation. 2 Fill-s memory between any 2 addresses to a specific byte - typically OO or FF. Merges memory blocks of data. Splits memory into two blocks of data. Finds string of up bytes long. 6 Calcu1ates the two byte (4 character) checksum between any two addresses. Carries qenerated by addition are ignored. Copies data block from any specified address to another part of memory: This operation is not al-l-owed if the new memorv block is not j-n the memory ranoe. B Changes the language used for prompts and error messages. Choose betweem English, French or German. Prints contents of memorv through the RS232C or Centronics interfaces. A Complements ( I's complement ) memory between any two addresses. B Special Functj-ons: This facility provides an entry to occasionally used functions and new enhancements. Change User: The programmer can store parameters, such as device type and l-ine parameters, for up to 5 users. The parameters l-ast used by a particular user are recorded when a new user is selected. D Hex Calcufate: Thj-s facility performs hexadecimal addition or subtraction and is useful for calcul-ating hexadecimal offsets when editing. E Change mode: This function al-ternates between "Production" and "R&D" mode. F Keyboard Unlock: If the current password is known, the keyboard can be locked. The password and/or the password level can be changed. 4. DETAILED OPERATING PROCEDUREFOR BASIC CONTROLS 4.L. Set device type, set details and byte order for 40 pin eproms This function enables the user to specify the device type, number of devices per set and organisation - B, 16 or 32 bit word. After pressing SET TYPE the display fl-ashes with the message: 'Enter device Number or EITHER enter the required device number, say, 27C7OO7. The L900O wil-I now search for the first device and show the manufacturer. If SET TYPE is pressed again the next Z7CLOOL, if dny, will be displayed. Note that the full- device number does not have to be entered. For example 2BF wil1 di-sp1ay the first device beginning 2BF. If the required device is selected but the manufacturer is wrong use the < STEP > to step to the correct device. It shoul-d also be noted that if a device number includes letters other than A to F, such as H, this l-etter should be left out. For example to select 6BHC7IL, simply enter 6BC7IL. OR press < STEP > to move to the next group of devices. For example if the current group is 27256s press STEP > to move to the 275L2s or preSs Having sefected the required group, press ACCEPT to confirm the group is correct then < STEP > to sefect the required device type fol-l-owed by ACCEPT. The number of ICs in the set can then be specified followed by the organisation. In production mode, the organisation is automatically adjusted accordj-ng to the number of ICs per set as fol-lows: - ICs per set Organisat j-on Organisation ( B bit eproms ) (16 bit eproms) 1 B bits 16 bits ) 16 bits 32 bits =A 32 bits 32 bits x 32 bits 32 bits If say 3 ICs per set is chosen, the setting is rounded up to 4. In R&D mode, the organisation can be changed. For example, a four IC set with a 76 bit word length could be selected. The set size must be consistant with the ram sj-ze. For example, a 4M bit ram vroul-d be required for a set of four lM bit eproms. If the set size was too large, the L9000 would not program or verify, etc., and an error message would be displayed. If the eprom is a 40 pin device, a further question would be asked to find out in which order the two eight bit bytes shoul-d be programmed. For Intel systems, the byte order is usuafly even bytes in DO - D7 with odd bytes in DB - D15. Motorola systems are usually the opposite ! Note that the devi-ce list is sequenced in three segments: eproms, includi-ng eeproms, micro-control-lers and finally eprom cards. 4.I. Set device type etc. (Continued) A device may be selected wj-thout one of the correct modules being fitted. However, the correct modul-e must be fitted before reading, programming or blank checking, etc. If the module has not been fitted, the operation would be aborted wj-th a request to fit the appropriate module. In some cases, there may be a choice of modules f or say DIL or PLCC devj-ces. The device list at the end of this manual specifies which devices have an Intelligent Identj-fier code. This code can be checked by the L9000. For these devices, dD extra question is asked to determine whether the user wants to check this code. Note that thi-s choice is stored for each user on power down. Essentially there are three choj-ces. The first choice is to ignore the code. The second choice is to check that the device and manufacturer code are both correct. The third choice al-l-ows the L9000 to program a mix of devices providing they are compatJ-ble. Whenever a new device has been chosen the check is reset to the defaul-t condition. When the L9000 is supplied, the default is to check the j-dentifier but it can be changed to turn off the check by using Special Function 6. 4.r. Set device type etc. (Continued) The Intelligent Identifier is a two part code which specifies the device manufacturer and type. Checking it helps to avoid the possibility of damaging eproms if the eprom seLected and the eprom fitted differ. Pl-ease refer to the App1j-cation Note in Section L6.2 for a full explanation. If a microcontroller is sel-ected, such as Intel- 87C51, it is possible to program one or more of the lock bits. The default is NOT to program any lock bits. With the PL332 MKII modufe first produced in December L994, it is possible to protect sectors on devices such as 29FO4O by selecting the device type 29FO40_SP. The user is asked to specify a mask. The least significant bit refers to the first sector, etc. For example, by specifyi-ng a mask of 000003, the first two sectors would be protected. In addition the STEP > key sets all- the bits in the mask for the current device and the STEP < cl-ears the mask. Erasing such a device removes al-l- sector protection. L2_. Program from ram This mode may only be selected from the INITIAL state" If necessary, change device type and set mode as described in para. 4.I. In R&D mode, the user j-s asked the ram start address. In production mode, the address is assumed to be 0. The L9OOO then works out whether there is enough ram considering the set size. If there is not, the function wil-I be aborted with a message: Insufficient ram for specified set size. 2. The copy devices must be bl-ank in production mode. In R&D mode, the device need not be blank but must be programmabfe. A test for programmability - 'IIIegaI bit test' - is performed if the device is not blank unless the device uses flash technology. In this case non blank devices are automatically erased in R & D mode but NOT in production mode. After completion of the pre- program checks, which are performed at just over 4.75V, all devices are programmed simultaneously. If a device fails to program, the L9000 continues with the remaining devices. 3. The program sequence follows the pre-program checks and the devi-ce(s) is then verified with Vcc set to just under 5.25V. In 'production mode', a second verj-fy at low Vcc is performed. (Most eprom vendors only recommend a single verify so this procedure is extremely thorough - see next section for detail-s of verify procedure. ) Lock bj-ts of mi-crocontrollers such as the B7C5l are programmed after ALL devices have verified successfully. Refer to the Application Note in section L6.4 for more details on programming fock bits. 4. During these procedures, the Z done j-s indicated on the display. 5. As a precaution against a user turning off the programmer and forgettj-ng that the ram data wil-l be lost, the L9O0O wil-l- not all-ow any device( s ) to be programmed from ram unless one of the following actions has been taken after turning on the programmer: Data must have been read j-nto ram from master device(s)., OR data must have been downloaded through one of the ports., OR data must have been edited usins the edit function. REMEMBERRAM DATA WILL BE LOST IF THE PROGRAMMERIS TURNED OFF. 4.3. Verify with RAM 1. This mode may only be selected from the INITIAL state. If necessary, change device type and set mode as described l-n para. 4.I. In R&D mode, the user is asked the ram start address. In production mode, the address is assumed to be O. The L9O00 then works out whether there is enough ram considering the set size. If not, the function will- be aborted with a message: "Insufficient ram for specified set size" 2. The L9000 stops verifying if it finds a discrepancy between ram and copy data. In such cases, the address, master data and copy data will be displayed and the green tight will- flash above the rel-evant sockets. If ACCEPT j-s then pressed, the L90O0 will carry on with verifying other devices. If STEP > is pressed, it wil-l al-so verj-fy the failed devices. (In production mode the detail-s of failed devices are passed over. ) 3. In production mode a two pass verify at both high and l-ow Vcc is performed. If the device manufacturer specifies that the device works at 5V + or - 1O?, the device is checked at these limits. The device l-ist at the end of the manual shows which devices have a 10E l-imit. 4. In R&D mode a single verify j-s performed at the high Vcc limit unless the device manufacturer specifies a two pass verify in which case a two pass verify is performed. 5. After verifying a set of devices the total checksum is displayed. However individual eprom checksums can be checked by using the STEP keys. The relevant eprom(s) are indicated by the appropriate copy socket lights. Note that if say two sets of devices are programmed both copy sockets lights will- be lit for j-denticaL eproms. 6 If the user has requested the programming of l-ock bits for microcontroll-ers, the program run ends with the message rLocked @ xxxx' where xxxx is the checksum. For more details on programming security bits, please refer to the Application Note in section 16.4. 4.4. Set communications parameters 1. This process may only be started from the INITIAL state. It enables the foll-owing parameters to be seen and/or changed. These parameters are automatically retained until next changed even if the power supply is disconnected. Confirmation that the parameters have been retained is given by the typical sign on message: ''LLOYD RESEARCH LTD'' "L9OOO V1.55 OBM Ram" If for some reason the parameters have not been retained, the second l-j-ne of the s j-gn on message would be: "W)Default parameters. " The foll-owing parameters may be set: Data input through? R5232 or Centronics para1J-el ports. Data output to? R5232 or Centronics ports. Baud rate? L9K2, 9600, 4BOO, 2400, 1200, 600. Data bits? 7 or B. Parity? Odd, even or none. Stop bits? 1 or 2. RS232 handshake? Soft - Xon/Xoff or Hard - DTR. CAUTION 1: Do NOT select the Centronics port for i-nput un1ess the remote computer has been turned on, because the L9OOO will continually analyse the signals on the Centronics port and the keyboard may become inoperative. CAUTION 2z If the Centronics port has been sel-ected for input & output, it will not be possible to turn the L9000 into remote controf from a remote computer. 4.5. Bl-ank check and erase fl-ash eproms 1. Thj-s mode may only be selected from the INITIAL state. If necessary, change device type as described in para. 4.L. Note that this function cannot be used for Texas 27C292. 2. If any devJ-ce has been programmed, the address and data woul-d be dispJ-ayed and the appropriate copy socket light woul-d fl-ash. To carry on blank checking the remaJ-ning blank devices/ press ACCEPT. Al-ternatively, press STEP > to carry on bl-ank checking all devices. 3. At the end of the procedure, the copy socket lights wil-l- be il-luminated for bl-ank devices whereas the lights will flash for failed devices. Note that, in the case of 40 pin eproms, the second line of the LCD can only show four separate devices because each device has two bytes of data. The actua1 faulty device is shown by the flashing 1ight. A In the case of fLash eproms such as 2BFO1O, the user has the choice of either performing the standard blank check or erasing the device. In the l-atter case, it is also bl-ank checked. If it is required to program the device immediately after the blank check, the user can simply press the 'Program from ram' button whj-lst the blank check is being performed. As the keyboard is buffered, the command is obeyed after the erase cycle. 4.6 . Check master Thj-s facility provides a simple method of checking a single master without reading the data into ram. The Intelligent Identifier is first checked if the device is specified in the device list as having an ldentifier and j-f the user has requested this check during the set type function. If the device is read-compatible with the selected device, it is read twice at high and l-ow Vcc. If the checksum is the same both times, it will- be displayed. If the checksum is different, a message 'Faulty device' - will be displayed. If the device j-s bl-ank, the word 'Bl-ank' wil-I be displayed. If the checks are successful, the copy socket light wj-Il be permanently illuminated. If an error is detected, the light wilI fl-ash, etc. If the Intelligent Identifier code is inconsistent with the eprom being checked, dD error message - 'Wrong type'- wj-lI be displayed instead of the checksum. If the eprom contains no Intelligent Identifier code and a check has been requested, a message - 'No code' - wiII be displayed. Section 16.2. contains an Application Note on the Intelligent Identifier. 5. DETAILED OPERATING PROCEDUREFOR RAM CONTROLS 5.1. Program from port 1. This mode may only be selected from the INITIAL state. If necessary, change device type and set mode as described in para. 4.I. 2. This function enabl-es the user to program one or more devices at the same time as downloading data to ram. This procedure is recommended for speed instead of 'downfoading data through either the serial or Centronics ports and then programming from ram' providj-ng the foflowing conditions apply: - Data is beJ-ng downl-oaded at l-ess than about 3O,OOO baud, AND - The device uses a programming pulse ( see device parameter list in appendix) of 2OOuS or less. 3. There are a few restrictions which apply to this procedure which do not apply to tProgram from ram', e.g.: - Devices must be bl-ank. - Certain algorithms ( some AMD & Texas ) are not suitabl-e for this method. - This method assumes that the 'Ram start' address is zero for the program and verify sequence. It can, however, b€ specified as non-zero for the download. 4. The procedure starts in a sj-miIar way to the rdownloadr f unctj-on and continues in a similar manner to the 'program from ram' function. As there j-s no need for data to be in sequence, the L9O0O cannot show the programming Z completed. Instead, however, the download address is shown as for the download function. After downloadi-ng and programmi^g, the data j-s verifj-ed with ram. 5. The checksum is shown after programming but it should be noted that the programming checksum will only be the same as the downl-oad checksum if al-I data bytes are downloaded. Bytes not downl-oaded are set to the blank condition ( FF for eproms ) . As part of the procedure, the ram is fil-led with FF and devices are bl-ank checked before programming. However, the sending computer can start to send data immediately after the ACCEPT button has been pressed for the 'Ram start' address. Any data received during the ram fill- and bl-ank check is stored. If the L9O00 data buffer fills up, the handshake (Xon/Xoff or DTR Lo for seria] data) wil-l be invoked. CAUTION: If for any reason the data transmisslon j-s hal-ted, the procedure should be stopped by pressing CANCEL. Under no circumstances shou1d the devices be removed when the red 'l-ive' light is on. Removing devices when programming voltages are present can l-ead to device destruction. 5.2. Read Master device( s ) j-nto ram 1. This mode may onJ-y be selected from the INITIAL state. If necessary, change device type and set mode as described in para. 4.I. In R&D mode, the user is asked the ram start address. In production mode, the address is assumed to be 0. The L9000 then works out whether there is enough ram considering the set size. If there is not, the function will be aborted with a message: "Insufficient ram for specifi-ed set size" In this case, the set size must be reduced or more ram must be fitted. 2. Data is then read into ram starting at the 'Ram start' address. If the L90O0 is in set programming mode - 2 or more ICs per set - and if one or more devices is missing from the set, this part of ram will unchanged. Note that eproms must only be fitted in the copy sockets corresponding to a logical set ( see Section 7 .2 for a full- explanation). Data is stored in ram according to the data structure of bits per word. In B bit mode, data will- be stored in consecutive ram addresses. In 16 bit mode, data will be stored i-n al-ternate locations. In 32 bit mode, data will- be stored in every fourth byte. 3. Progress is indicated in I during reading. 4. After devices have been read, the checksum wil-l- be displayed and the relevant copy socket lights will be ill-uminated. 5. After reading a set of devices into ram, it can be useful- to check the j-ndividual checksums of each eprom. This can be done by using the STEP keys. The display shows the checksum for each device. The refevant eprom is j-ndj-cated by the copy socket 1ight. 5.3. Verify wj-th port 1. This mode may only be selected from the INITIAL state. If necessary, change device type and set mode as descrj-bed in para . 4.I. 2. This procedure enables the user to compare a file of data on a computer to ram data which may have been read into ram from one or more devices or another computer f il-e. 3. Whil-st data is being read into ram, any differences are displayed on the LCD for a few seconds. 4. An appropriate error message indicatj-ng whether or not the data bl-ocks are j-dentical is displayed at the end. 5.4. Download data to L9OOO 1. This facility allows data to be downloaded from another computer system such as a PC or mainframe. 2. Set up comms. parameters and port to be used as described in section 4.4, using the SET COMMS function. For speed, the parallel port is recommended. This is about 5 to 6 times faster than the serial port of a typical PC running at 9,600 baud. 3. Press DOWN LOAD. The programmer displays the current data format for a possible change by usi-ng one of the STEP keys" Alternatives are Intel, Motorola S, Tektronix, Ascii hex space or Binary formats. Extended address records are catered for. 4. The 'Load data from' address is next requested. This is the address of the first byte to be read from the data being downl-oaded. 5. The 'Load data to' address is next requested. This j-s the address of the last byte to be read from the data being downl-oaded. It must be higher than the 'Load data from' address. The di-fference between these addresses must be l-ess than or equal to the ram size. If the address is not valid, the questions will- be repeated. Note that this address can be calcul,ated automatically, according to the current set size and the rload data from address', by pressing STEP 6. The'Ram start' is next requested. Thj-s is the address where the first byte will- be stored in the programmer ram. It is checked as follows: 'Ram start' < or = 'Load data to' - 'Load data from' This condition ensures that data wilf not overffow because the ram is too smal-l-. 7. The L90O0 now di-splays a message to show which port is expecti-ng data. B. Once data transmission has started, the address currentl-y being downfoaded will be displayed. 9. After downloading al-I data, the checksum wi-Il be di-spIayed. f 0. Def aul-ts for downloading are the same as l-ast used for up- or downfoading. 5.5. High speed downl-oad util-ity 'COMPRESS' l. Introduction For most applications, COMPRESScan be used J-n place of the DOS COPY command to speed up the downloading of data files to an L9000 programmer in Intel- hex, Motorofa S records or Ascii hex space. P]ease note that COMPRESS cannot be used on binarv or Tektroni-x f i-Ies. COMPRESS works by reducing the number of bytes transmi-tted through either the serial- or the paral-l-el port whilst maintaini-ng all- checksums. It has also been designed to share the processing between the PC and the programmer. Bel-ow are some examples of the savings which can be expected. You can try the demo program with the demo fil-es to evaluate the saving on your own PC. For maximum saving, copy the fil-es from the demo disc onto your hard disc. (You will- need half Meg. byte free on your hard disc). Note that the Live version is j-nstall-ed using an install-ation program - INSTALL. THE DEMO PROGRAMWILL ONLY DOWNLOADTHE FILES PROVIDED!

With programming times of about 42 seconds for a typi-cal lM eprom, it is now possj-bl-e to download data for a 1M eprom and to program it in about 52 seconds. Note that COMPRESScan be used over a network providing the port being used is NOT the fi-Ie server port.

How to use COMPRESS COMPRESS is al-most j-dentj-cal- to the COPY program. e.g. to downfoad the demo fil-e - DATA. INT - using the Centronics port, type: COMPRESSDATA.INT PRN: The f ull- syntax is: COMPRESS Idrive: ]pathname portname optj-on Port names are: COM1z COM2: etc. for R5232 seria1 port PRN1: PRN2: etc. for Centronics parallel port Un1ess the option /+ is used (see option 1 below), the RS232 serial port MUST be set up using the DOS MODE command. Options 1: A specj-a1 opti-on is avail-abIe to increase the baud rate to L9,2OO baud. (On most PCs, DOS can only set the baud rate to 9,600 baud. ) /+ sets the RS232 port to I9,2OO baud, B data bits, Do parity, I stop bit. (The previous status of the port is restored after COMPRESShas ended. ) Option 2z A second option is avaifable to suppress the message which is displayed after each fj-le is compressed. option = /- to inhibit termination message. option = /+- or /+/- to combine both options. Option 3: To display help in languages other than English use the following option by itself. COMPRESS/F Displays heJ-p in French COMPRESS/G Displays help in German Examples: 1. To copy a file called data.int from your current working drive and directory to the RS232 seri-al port COMl. COMPRESSDATA. INT COMI: 2. To copy the same file as above at the fastest possible speed by setting the R5232 port to I9,2OO baud. COMPRESSDATA.INT COM]Z /+ 3.

You can try COMPRESSon your PC with the demo files which contain data for a L/4 Mbit eprom such as 27256. DATA.INT contains data in Intel- format; DATA.MOT contains data in Motorol-a format; DATA.ASC contains data in Ascii hex space f ormat. Proceed as for normal- downl-oading with: Load data from address 00000000 Load data to address 00007FFF Ram start address 00000000 5.5. High speed download utility - 'COMPRESS' Examples (Cont. ): 5. To display HELP information: COMPRESS Al-te,rnatively you can print the ascii text fj-Ie - LRCHELP.D. Afternative suffixes are F for the French version and G for the German version. 3. Compress Instal-l-ation The l-ive version of the COMPRESS program has to be instal-Ied onto your system from a master dj-stribution disc. To install COMPRESS, insert the distrj-bution disc into the floppy drive. Change the DOS prompt to the drive (e.9. "A:(Enter)" for drive A). Now run the INSTALL program from the specified drive ( e. g. " INSTALL" ) . The INSTALL program will prompt you for the required "drive" and "directory". To run COMPRESS from another directory, add the installed directory to the PATH. CAUTION: 1. COMPRESSis a licensed product sold for use by a single user. DO NOT ATTEMPT TO INSTALL COMPRESSFROM A COPY OF YOUR DISTRIBUTION DISC - IT WILL NOT WORK! 2. It is important to use a good quality screened data cabl-e with twisted pairs to connect the L9000 to the Centronics port of a PC. Ribbon cabfes or simple screened cables may give rise to data errors which will- be detected by the L9OOO as checksum errors. 5.6. Upload data from L9OO0 1. This facility allows data to be uploaded to another computer system. z- Set up comms. parameters and port to be used as described in section 4.5, using the SET COMMS function. 5. Press UP LOAD. The programmer dj-splays the current data format for a possible change by using one of the STEP keys. The main formats are Intel-, Motorola S, Tektronix, Ascii hex space or Binary formats. Extended address records are catered for. The L9000 then requests a terminator byte to transmit. This byte is transmitted after al-l data has been uploaded. Typicafly, this byte is set to some convenient val-ue such as 1A (ControL Z) so that the software of the recei-ving device can recognize the end of fil-e. If no termj-nator is reguired, the recommended settj-ng is 00, corresponding to a nul-l byte. This question is omitted for binary formats. A The rl,oad data from' address is next requested. This is the address of the first byte to be transmitted from the L900O. The rload data to' address is next requested. This is the address of the last byte to be transmitted from the L9OOO. It must be higher than the'Load data from'address. The difference between these addresses must be less than or equal to the ram size. If the address is not va1id, the questions wj-Il be repeated. Note that this address can be calculated automat j-ca1Iy, according to the current set size and the 'Load data from address', by pressing STEP 6. The 'Ram start' is next requested. This is the address where the first byte wil-I be taken from in the programmer ram. It is checked as fol-Iows: 'Ram start' < or = I Load data to' - 'Load data from' This condition ensures that data will- not overf.l-ow because the ram is too smaLl. 7. The L9OOO now dispJ-ays a message to show which port is being used. B. Once data transmi-ssion has started, the address currently being uploaded will be displayed. 9. After uploading al-1 data, the checksum will be displayed. 10. DefauLts for upioading are the same as last used for up- or downloading. 6. pElAItEp OPERATTNG PROCEpUREFOR HEXApECTMAL/EDTTTNG KEYS 6.1. Edit ram 1. This mode may only be selected from the INITIAL state. It is used to change individual- bytes of ram. 2. After pressing hex key L, the edit start address is requested. The address must be a valid ram address. 3. The L9000 then displays the hex data and the ascii symbol for that vafue. Data can be changed by entering a new hex value. Note that, if it is required to change a byte from say'F6'to '03', then ej-ther'O3'or'3'can be entered. The leading 0 is automatically inserted. The STEP keys will step to the next address. 4. The function can be terminated by pressing ACCEPT. 6.2. FilI ram to predetermj-ned value 1. This mode may only be selected from the INITIAL state. It is used to set a selected range of ram to a specified val-ue. 2. After pressing hex key 2, the ram filt start address j-s requested. The address must be a valid ram address. 3. Next, the ram fil-l- end address is requested. The end address must be higher than the start address and it must afso be a valid ram address. 4. The ram fill byte is then requested. 5. The address being f ill-ed j-s shown every few seconds. 6. At the end of the procedure, the limits fil-led are displayed together with the ram fil-I byte. 7. If val-id addresses have not been entered, the questions wi-II be repeated. 6.3. Merge data blocks 1. This mode may only be selected from the INITIAL state. It is used to merge together two blocks of memory which have previously been sptit for a 16 bit system. 2. After pressing hex key 3, the programmer merges two bl-ocks of B bit data into one bfock of L6 bit data. The even bytes should be in the lower hal-f of ram starting at 00000 and the odd bytes in the upper hal-f of ram. The upper half of ram depends on the ram size as f ol-l-ows: L9OOO OBM Ram 00080000 L9000 04M Ram 00040000 L9OOO O2M Ram 00020000 ? Approximate progress of the merge is indicated by a reducing count. 4. The merged data block starts at ram address 0. Consider an exampl-e of mergi-ng two b1ocks of ram: 1st Bl-ock 2nd Block BYte O = 00 Byte 80000 = 40 Byte 1 = o1 Byte 80001 = 4L Byte 2 o2 Byte 80002 = 42 Byte 3 o3 Byte 80003 = 43 The new bl-ock starts at hex address 0: OO 40 01 4L 02 42 03 43 NOTE: Data from two master eproms can be merged automatically by specifying 16 bit data when using the SET TYPE facility. These devices can be read i-nto ram at Ram start O. 6.4. Spl-it data bl-ocks 1. This mode may only be selected from the INITIAL state. It is typically used to sptit L6 bit data into 2 blocks of 8 bit data. After the split, the bl-ock containing even numbered bytes starts at 0. The block containing the odd numbered bytes starts at the first address of the upper hal-f of ram. The upper hal-f of ram depends on the ram size as foll-ows: L9O00 OBM Ram 00080000 L9OOO O4M Ram 00040000 L9OOO O2M Ram OO02OOOO 2. Approximate progress of the split is indicated by a reducj-ng count. Consider an exampl-e of splitting a ram block: Byte O : OO Byte 1 = 01 Byte 2 = 02 Byte 3 = 03 Byte 4 = 04 Byte 5 = 05 After the split, there woul-d be two blocks as fol-Iows: (This example assumes a ram size of BM bits. ) Bl-ock 1 Block 2 Byte O = 00 Byte 80000 = 01 Byte 1 = 02 Byte 80001 = O3 Byte 2 = 04 Byte 80002 = 05 NOTE: This function is performed automatically when using the Set programming facility by specifying 16 bit data. For example, two eproms can be programmed with 76 bit or 32 bit data by specifying the number of data bits when setting the device type. 6. s. Fi-nd character string and replace 1. This mode may only be entered from the INITIAL state. It is used to fj-nd a string of up to B hex bytes between specified li-mits in ram. Don't care brztes are af lowed. 2. Press hex key 5. The required start address in ram must be entered, then press ACCEPT. The default is the last used address. 3. The last ram address must be entered, then press ACCEPT. The default is the l-ast address used. The last address must be higher than the f i-rst address. 4. The first byte must now be entered. The ascii character is shown. For example, if hex byte 32 is entered, the ascii character 2 will be displayed. If the first byte is a don't care term, simply press STEP string, simply press ACCEPT. q To enter a second or subsequent byte, press STEP > and repeat the procedure. 6. If the character string i-s found, the EDIT RAM procedure will be entered as described j-n para 6.1. A search for another occurrence of the string can be started by pressing ACCEPT. If the stri-ng is not found, an end of function message will be displayed and the programmer wil-l return to the INITIAL state. 6.6. Checksum between specified ram addresses 1. This mode may only be selected from the INITIAL state. It is used to compute the 2 byte (4 hex character checksum) between 2 user specified addresses. 2. Press hex key 6. The L9000 requests the start address. Enter a val-id ram address and press ACCEPT. 3. The L9000 then requests the checksum end address. This must also be a val-id ram address which is also higher than the start address. 4. Press ACCEPT after entering the upper l-imit. The L9O0O then adds each byte to an accumufator and displays the resultant checksum which corresponds to the 16 bit addition of all ram bytes with carrj-es ignored. The address currentLy being 'checksumed' is displayed every few seconds. 6.7 . Copy block of ram data 1. This mode may only be selected from the INITIAL state. It may be used to re-arrange data in ram. The data bfock to be moved is called the 'source' bfock. The source bl-ock is moved to the destination block. There are no restrictions regarding where data is moved to and the L9000 al-l-ows the source to overlao the destination block. z. Press hex key 7. The source block start address is then requested. Thi-s must be a valid ram address. Press ACCEPT. The source block end address is then requested. This must be higher than the start address and it must al-so be a valid ram address. Press ACCEPT. 4. The destinatj-on address is then requested. This must also be a valid ram address. The L9000 then works out the destination bl-ock end address and checks that there is sufficent ram. Press ACCEPT. ( If i-nvalid addresses have been entered. the questions will be reoeated. 6. Whilst moving data, the byte 'currently being moved' is displayed every few seconds. Note that, for this function, data blocks may overlap in spite of the address being displayed which is for information onlv. .7 This function ends with a message showing the first address of the source and destination b]ocks. 6. B. Change language 1. This facility changes the text / prompt language between English, French or German. 2. Press hex key B. The programmer requests the required language. Step > or Step < to change language. 3. Press ACCEPT when the required language has been selected. A11 future text messages and prompts will appear j-n the requj-red language. 6.9. Print ram l. This mode may only be sefected from the INITIAL state. The contents of a specified part of ram will- be output to the RS232C or the Centronics port. The port and line parameters must previously have been defined using SET COMMS. 2. Press hex key 9. The L9OO0 requests the first address from which to print. Enter the required address which must be a valid ram address and press ACCEPT. 3. The L90O0 requests the last address to which to print. This must also be a val-j-d ram address which is a higher address than the start address. 4. The printout takes the form of a hex dump with the equivalent ascii character. 6.10. Complement ram between specified ram addresseg 1. This mode may only be sel-ected from the INITIAL state. The contents of a specified part of ram is complemented ( 1's complement ) . 2. Press hex key A. The programmer requests the first ram address to complement. Enter the required address, which must be a valj-d ram address, and then press ACCEPT. 3. The L900O then requests the last address to be complemented. This address must al-so be a valid ram address which is higher than the start address. Press ACCEPT. 4. The L90OO displays the address being complemented every few seconds. 6.11. Special functions This mode may only be selected from the INITIAL state. Press hex key B to sel-ect 'Special functions'. The STEP keys can then be used to sefect the required function or the relevant hex key can be pressed. 0. Press key 0 to display software release year and month. Note that there coul-d be more than one release in any one month. 1. Press hex key 1 to display the model number ( L9OOO), software revision number & ram size. This message can be read remoteJ-y. 2. Press 2 to check hardware calibration. A warning message to remove proms is displayed. After removing any devices, press ACCEPT. The programmer now halts and puts cal-ibration voftages across three preset potentiometers. To check these voltages, the bottom of the instrument must be removed. Note that some screws also retain the feet. There are three preset controfs which are identified on the track-side of the board. The voltage across the ends of the presets must be measured on a 4 I/2 digit DVM or simil-ar instrument after a warming up period of ten minutes. The voltages are: RVl 25.OV +/- 0.lV RV2 6.00V +/- 0.05V RV3 6.00V +/- O.O5V It is also recommended that data should be downloaded to the programmer from a computer whose clock frequency is known to be accurate within LZ. If there is no hardware error for say 10 bytes of data, i-t may safely be assumed that the clock frequency is correct for the L9000. This ensures that the program pulse widths wil-I also be correct. Alternatively, the clock frequency may be checked on pins 15 and 18 of UI2 counter timer as 1.843 MHz. TO RETURN THE PROGRAMMERTO NORMAL OPERATION TURN IT OFF FOR AT LEAST A MINUTE. A 'Local' z+- Press hex key 4 to display the method of controf. Either or tRemote' will- be displayed. 6. Press hex key 6 to display the InteJ-ligent Identifier defaul-t. If this is yes, the Intelligent ldentifj-er check wj-ll be turned on whenever a new device has been selected. If this is Do, the check will- be turned off whenever a new device has been sel-ected. The Application Note in Section L6.2. explains the operation of the Intelligent fdentifier in full. B. Press hex key B to display the modul-es fitted. If the L9000 software fitted does not recognise the module, a number will be displayed. In these cases, there is either a faul-t or a later version of software is needed. 6. 11. Special functions ( Continued ) 9. Press hex key 9 to enter the hex code to action the remote control- command string. Default = ODH (Carriage return. ) 10. Press hex key A to enter this function. This function enables the user to increment a number in ram which is typical-Iy a serial number. The parameters set up by this function are: Number base (Binary or decimaf), length of number and which end of the byte string has the low or high byte. When these parameters have been set up it is possible to increment or decrement a byte string by remote control. t1 Press hex key B to print the L9000 device list to the currently selected output port. The output port can either be the RS232 or the Centronics port as sel-ected using the Set Comms. function. The function can print the compl-ete device l-ist, the device list for one manufacturer, or a range of manufacturers. Between one and 99 copies can be pri-nted. The listi-ng aLso shows the version number and the date on which the sof tware was rel-eased. Devi-ces are fisted by manufacturer wj-th 5 devices per l-j-ne giving a maximum of 69 characters per line. The number of characters per l-ine has been restricted to 69 so that l-aser printers can be used to print di-rectly onto A4 paper. Currently the device list can be printed on 3 sides of A4 paper. To print a fuIl list, press ACCEPT when the L900O requests the manufacturer at which to start printing and press ACCEPT again when the L9OOO requests the manufacturer at which to stop printing. For a partial listing of say Texas Instruments devices, use the STEP > to scrofl to this manufacturer for the start and press ACCEPT to set thls manufacturer as the l-ast manuf acturer as well-. The L90OO will- then just print Texas only devices. To print say Texas and Toshiba devices, foll-ow the above steps but set the l-ast manuf acturer to Toshiba i-nstead. When selecting manufacturers, the L90O0 displays a code as wefl as the name of the manufacturer. This is the 'manufacturer code' used as part of the Intelligent Identifier check. Some manufacturers, such as Intel, have two codes so they appear twice. Also, note that GI and Microchip have the same code because they are the same company. 13. Press key key D to select the slave address of seriaf eeproms such as 24Cxx. This setting is used to set both hardware and software addresses when programming 24Cxx devices on the PL30B modufes. Note that if devices are programmed with the PL30B modul-e the setting is irrelevant. However by selecti-ng the appropriate address it is possible to connect the L90O0 to an external I2C bus and program a selected device. It is possibie to have up to eight 2K devices on an I2C bus so the possj-bJ-e va.l-ues of this address are 0 to 7 . Note however that as device size increase the the number of devices on the bus decreases. For example there can only be 4 x 4K (24CO4) devices. The possible addresses for these devices would be O, 2, 4 or 6. 6.L2. Change user and parameter storage 1. This mode may only be sel-ected from the INITIAL state. The facitity enabfes one user to store his parameters whil-st another user is using the programmer. In fact, parameters may be stored for up to 5 separate users. User parameters include R5232 parameters, choice of port, devj-ce type, access speed, number of ICs per set, bits per word, data format for upr/downloading, terminator for uploading, Load at and l-oad to addresses for downloadi.g, password and password l-evel. 2. Press hex key C. The display shows the current user. A new user number - 1 to 5 - can be entered. Press ACCEPT to end. 6. 13. Hexadecimal cal-culations 1. Thi-s function may only be selected from the INITIAL state. This facility performs 2 byte hex addition or subtraction. The 3 byte resul-t is displayed. The first byte pair default j-s the value previously used so that it can be used as a constant. 2. Press hex key D. The displays shows the fast value entered. A new value can be entered. The arj-thmetic operator + or - can be changed by using one of the STEP keys. Press ACCEPT. 3. The second value may now be entered. The arithmetic operator + or - can be changed by using one of the STEP keys. Press ACCEPT. 4. The L9OOO displays the answer. 6.L4. Keyboard password 1. This mode may only be sel-ected from the INITIAL state. This facility provides a simple means of ensuring that the more complex functions can only be used by people who know the password. The password 'Ievel' can be set by the user so that the point at which the password must be known is appropriate. For exampfe, in a production envj-ronment when the programmer is being used to copy one particular device, it may be desirable to stop the device type being changed. 2. The programmer requires the user to enter a 3 character password to l-ock or unlock the keyboard. The user can then change the password. Whenever the password is changed, the user can reset the password to one of 4 l-evel-s. 3. Each function has a password l-evel-. Level 4 is the highest l-evel and is specified for the most complex functions. For example, if the password is set at level 3, all- functions can be performed without the password except those at l-evel- 4. The password level for each function is shown in Appendix 1. 4. The procedures for locki-ng and unlocking the keyboard are identical. OnIy locking is, therefore, described. If at any time the programmer 'l-ooses' its parameter information, the password wil-l- be reset to the default val-ue of 00O. If the password is set and forgotten, contact the manufacturer or your distributor. Press hex key 0 (F to unlock). Enter 3 character password using any of the 16 hexadecimal keys. 6. Press ACCEPT after entering the password. If the entry was incorrect, the question woul-d be repeated whereas if it was correct, the new password would be requested. The default is the existi-ng password. Enter new password if required. 7. Press ACCEPT after entering the new or retaining the ol-d password. If a new password is given, a new level can be set. B. Enter a new password level which must be in the range 1 to 4. q The programmer wil-l- return to the INITIAL state after a second. 7. SET FACILITIES 7 .7. GeneraL The term - 'Set programming' - is used j-n thj-s manual to describe the ability to program more than one device simultaneously with different data. Set programming is used whenever the user specifies more than 1 IC per set. The programmer can program up to eight devices simuftaneously providing that the data can be contained within the memory. The way data is programmed into the devices is dependent on the data word length. If the data has eight bits, then the first data block woufd be programmed into the first device and the second data block would be programmed into the second device, etc. If, however, the data has sixteen bits, the odd ram bytes woul-d be programmed into one device and the even into the other. The Set parameters must be entered using the SET TYPE facility as described in para. 4.I. If, therefore, there are four devices in a set, simply answer the question 'ICs per set? 1 t with a 4. Note that entries are always rounded up to the nearest set size above the entry. If 3 is entered, a set size of four is used. 7 .2. Which sockets to use For eproms with an B bit data bus: The right-hand socket is always programmed with the least significant data byte. For B bit data, therefore, the right-hand device woul-d contain the first data bl-ock and the device next to the right-hand socket would contain the next data block, etc. For 16 bit data, the right-hand device would contain the first, third and fifth bytes of data and the device next to the right-hand device would contain the second, fourth and sixth bytes. If there were say 4 ICs per set with sixteen bit data, the right-hand pair of devices wou]d contain the lowest bl-ock of data and the left-hand paj-r woul-d contain the highest block of data. For eproms with a 16 bit data bus: The PL40O can be supplied with one, two or four copy sockets. In the case of the PLAOO/A, the two right-hand sockets will always be programmed with identj-cal- data. Similarly, the two lef t-hand sockets wil-I also al-ways contain the same data. To program two devices with 32 bit data, therefore, use one socket on the right- hand side of the module and one on the left-hand side. If two sets of eproms are required, load al-I four sockets. Please note that the two lef t-hand devices will- contain i-denti-cal- data and, sJ-mi1ar1y, the two devices on the right-hand side wil-l also contain identical- data. The PLAOO/2 is supplied with one socket on each side of the module and, hence, these compli-catj-ons do not arise. To read a pair of devices into ram, do NOT place them on the same side of a PL4OO/4 module. Instead, the device containing the lowest two bytes shoul-d be placed on the right-hand side and the device containing the highest two bytes should be placed in one of the sockets on the l-eft-hand side. The PL60O module works in the same 7 .3. Making mul-tip1e sets of copies For eproms with an B bit data bus: Muttj-ple sets of devices can be made automatically by simply putti-ng devices into spare sockets. For example, therefore, to make two sets of two devices, simply put four suitable devices into the right-hand (or left-hand) group of copy sockets. The left-hand pair of devices wj-ll contain the same data as the right-hand pair. To make four pairs, simply put another four devices into the left- hand group of sockets. Note that it is possible to program parts of sets by si-mply omitting devices. Example of set programming four sets of two 32 pin devices using two PL3OO/4 modul-es: <-PL300- > <-PL300- > 2r 21 2r 21 Eproms wi-th an 16 bit data bus: Multiple sets of devices can be made automatically by putting devices into spare sockets. For example, therefore, to make two sets of two devices, simply put four devices j-nto a PLAOO/A or use two PLAOO/2 modules. Note however that, unlike the PL30O module, the two devices on the right*hand sj-de of the PL4OO/4 module wil-I be identical and, siml-larly, the two devices on the left-hand side will- also be identical-. Programming will be found to be a little quicker if only one socket of the l-eft- or right-hand pair on the PL4OO/4 is used. Example of set programming four sets of two 40 pin devices using two PL400/4 modules: <-PL400- > <-PL400- > 22 11 22 11 7 .4. Important points about Set programming 1. Set programming is ignored when b1ank checking. 2. When reading 16 bit data into ram from a master device, data is stored in every al-ternate ram byte. With 32 bit data, data is stored in every fourth byte. 3. When loadi-ng ram from a port, data is always stored according to the record format specified. The set programming details are i-rrelevant. 7.5. Valid start addresses When programming sets of devj-ces, it is important to appreciate that increasing the number of ICs per set increases the ram needed. For example, if there were four tM bit eproms j-n a set, the programmer woul-d need 4M bits of ram. However, the organisation of a B, 16 or 32 bj-t word does not alter the ram requi-rement. When starting to program, verify or read master devices, the L9000 checks that: - Ram start + (No. of ICs per set X Device size) < or = Ram size. If there is insufficient ram, an error message is displayed: Insufficient ram for specified set size The remedy is either to fit more rarn or to reduce the set size. 7.6. Programming sets of 4 devices with 2 socket modules Sometimes it is required to program a set of four eproms when only two socket modul-es are available. To copy a set of four eproms fit two 2 socket modules such as PL3OO/2 or PL45O/2 and then sel-ect B devices per set with say B bj-ts per word. Read the four masters into ram. Replace the masters with b1ank devices and program from ram. Using this method the user ram must be at feast twice as large as the set size. It is also possible to program a set of four devices with 32 bit data after data has been down loaded to ram. Select 4 ICs per set with a 32 bj-t word. Program two devices from the required ram start address normally O. The right hand device will contain bits O to 7 and the left hand device bits B to 15. Program the second paj-r of devices with the ram start address + 2. The right hand device will- contain bits 16 to 23 and the l-eft hand device bits 24 to 32. B. REMOTE CONTROL 8.1. General Any function except Keyboard lock/unlock, can be control-l-ed remotely using the RS232 or Centronics ports once remote control has been i-ni-tiated. A single Ascii character is al-located to each key. Receipt of this character, followed by a carri-age return, inj-tiates the same action as local operation. After each successful operation, program, verify etc, the L9OOO responds wj-th a prompt '+'. If the command coul-d not be understood or if the command was unsuccessfuf, the L9OOO responds with a negative prompt '-' . There are options to suppress the prompt and the local echo. Optionally the local keyboard can be totally dis- abled. The carriage return character can be changed using special function 9. Val-id characters in the range 01h to 29h except for NULL, ESC, XOFF, XON, SPACE, QUOTE. The R5232 port j-s recommended for remote control if the user wants to control- the programmer in great detaj-l and to monitor operations. The Centronics port is recommended for fast data transfer. It is feasibl-e to use a mixture of both. 8.2 Entering remote control The L9O00 always powers up in l-oca1 mode. Remote control- can be entered any of the foll-owj-ng methods: 1. Using the "Special function" facil-ity on the programmer. (See section 6.11.4. ) The user is also asked whether the prompt and /or echo options are required. The defaul-t is yes. ^ 2. Sending a | I character to whichever port is defined as input by the'Set comms' function on the keyboard. This character and all future commands are echoed back to the port selected for output by the 'Set comms' function. This option should only be chosen if the L9000 is connected to a control-ler with a bi-directiona.l- port. A standard PC does not have a bi-dir:ectional port so the next option is recommended for PC use. 3. Sending a'Z'character to whichever port is defined as input by the 'Set comms' function on the keyboard. The programmer is immedj-ately switched to remote control-, but the prompt and echo are suppressed. 8.3. Disabl-ing the keyboard Once the programmer is in remote operation, a special command 'H' disables the l-ocal- keyboard untj-l the L9000 i.s powered up again or ^ untj-l- a fresh t I is received. The programmer shoul-d be in the INITIAL state when this command is sent. Note that, with software versions prj-or to 2.37, dD 'H' put the L9000 into remote control whereas with versions 2.37 and beyond, the 'H' command does NOT put the L900O into remote mode. 8.4. Entering remote control- commands Once the remote mode has been entered, the input port is continuously scanned. Any character received is monitored. Assuming that there has been no hardware error, such as a parj-ty fail-ure or framing error, the programmer assumes that the character is a remote control- instructj-on and trj-es to obey it as though the relevant button had been pressed on the keyboard. Certain additional- characters have been introduced to remove the need for a programming language in some cases. For example, the device type can be set dj-rectly as can the up/download format. B.s. Error detection and correction Errors can only be reported to the user if the prompt is enabled. As already explained, remote commands can be grouped together on a l-ine and terminated by a carriage return. When the L900O has finished these commands, it sends a prompt character back to the controll-er. If no errors have occurred, the prompt woul-d be a '+' . If an error has been found or if a command has not been understood, a | - | prompt woul-d be sent. The control-Ier shoul-d then send a t-t back to the L90O0 whereupon the L9000 would send the two line error message back to the controller. The error buffer would then be cl-eared. The user shoul-d note that the L900O always records the first error if there are more than one. If an inval,id command has been received, a t - t prompt woul-d be returned to the controller, unless the focal echo has been turned ' of f . The f j-rst line of the display would show Inval-id command' and the second woul-d show the character. The L9000 woul-d be returned to the INITIAL state and the copy sockets woul-d be powered down. This is very similar to pressing CANCEL on the keyboard. The function must, therefore, be started again. Note that the L9OOO remains i-n remote mode until- it has been returned to .l-ocal. B. 6. Return to Local- only operation The L9O00 can be returned to local- only operation using the special function command which can be performed remotely. B4[G Select special functions (B) . Then press hex key 4 and step back to Local. As with al-l- remote control commands, no acti-on wil-I be taken until a carr:iage return has been received. 8.7 . Reading the display from the Controller ' The readback command /' causes the L9000 to transmi-t the current message on the two Line display to the control-ler as two separate l-ines. Each l-ine starts with a '? B. B. Software considerations The ability to download a command file means that simple Ascii files can be used to contro1 repetiti-ve command sequences. These are typically found in R & D applications where it is required to download a fil-e after compiling a program and, in production, where certain pre-defj-ned jobs need to be done. There is no need to al-.Iow any delay between transmitting data fil-es and command fil-es or vice versa. Note, however, that whilst command fil-es can use l-ower case characters, data fj-les must use upper case characters A F. Upper case throughout is recommended. Avoj-d data fil-es which have any text after the end of fil-e record. Thj-s text wil-l- be I-nterpreted as remote controf instructions. Typically, remote control commands can be created as a one line file which must be terminated by a carriage return. For documentation purposes, notes can be added at the end of each fine. Al-l- characters between a 'i' character and the next carriage return are J-gnored. ' Some of these instructions have notes prefixed by ;' as examples. If you are using an IBM PC or compatible, batch fil-es can be used, e.g. a task might be defined as JOB1. A fj-Ie JOBI.BAT would be created with a number of COPY commands to copy a mixture of remote control- commands and data to the paralle1 or seriaf ports. (See application note L9OOO No. 1 - Remote controf for examples. ) Note also that the DOS PRINT program can be used. The advantage of this is that the data is then transmitted in background mode, thus enabling the user to use the computer at the same time. 8.9 . Hardware considerations The remote control-ler must be compatibLe wi-th the L90O0. In the case of serial- devices, the R5232 hardware parameters must be the same. Under most circumstances, the highest possible baud rate should be used for fast data transfer. Note that if a hardware error occurs, such as a framing error, it is necessary to press CANCEL on the programmer. 8.10. Remote Control Commands 0 - F Hexadecimal- keys. G Acceot or GO. H Disabl-es kerzboard of L9OO0. I Download or Input data. After this instructi-on the data transfer format can be set: A Ascii hex space B Pure binary. D Dec. binary. E Extended Tektronix H Binary with header = FF. I Intel- M Motorol-a T Tektronix K Blank check. Shows which lights are on or flashing. Eight bytes are returned to the controller with the following meaning:- Light off. F = Light flashing - test failed. P = Light on - test passed. The first character received is for the l-eft-hand socket of the l-eft-hand module whether or not it has been fitted. This function can only be initiated from the INITIAL state. o Upload or Output data. After this instruction, the data transfe.r format can be set as for downl-oad. Program devices from ram. Reads master device into ram. S Set comms. The port is chosen by the next instruction: I RS232 port. I Centronics. T Set type. This instruction can be fol-lowed by the STEP command or a special method of settj-ng the device type. T"27C256 Tex" sets the device type to 27C256 Texas. The quote signs around the device type and make are essential. Note that this instruction sets the set size to 1. Verifies the copy sockets with ram. Verifies the port with ram. Programs devices from port. B. 10. Remote Control Commands (Cont. ) * Cancel. Subsequent commands wj-11 be obeyed. t Step l Step Increment serial number. Decrement seriaf number. Reads back both lines of current message in display. Reads back first error message, then cl-ears error buffer. ESC The current command is terminated and all other commands ( lBhex ) are abandoned. Space Command ignored. 8.11. Incrementing/decrementing serial numbers in ram Provj-di-ng the serial number parameters have been set up using the 'A' Special function , it is possi-bJ-e to increment a decimal- or binary serial- number. It is important to note that the seriaf number parameters must be set up, as described in section 6.11.10 of the manual, each time the programmer is powered up. The serial number is edited using the EDIT functj-on and by sending a t The programmer is fitted wj-th an RS232C serial port. The port socket is a 25 way 'D' connector at the rear of the instrument. The socket i-s wired as a DTE interface which means that it can be connected directly to another computer with a DCE interface. If it is required to connect the programmer to another piece of terminal equipment such as a printer, it will- al-most certainl-y be necessary to cross over connecti-ons: 2 and 3, 4 and 5, 20 and 6. This is shown below. 9 .2. Connection detail-s PIN NO. PURPOSE TITLE Output Transmit data This line carries the data sent from the programmer to the externaf computer.

General Data may be transferred to and from the programmer in several data formats namely: Intel, Motorola S, Tektronix, Ascii hex space or Binary. Since there are slight variants in the use of these formats, this section defines the i-mplementation of this product. A useful feature of the programmer is the ability to transmit a terminator byte after uploading data. This enabl-es general purpose software to be used by the remote computer. If the terminator is not required, the terminator should be set to 'OO' corresponding to a null- byte. The defau1t val-ue of the terminator is the val-ue l-ast used for the format in question. The terminator is omitted for binary formats. With effect from version 2.I5, the L9OOO wil-I accept lower case ascii characters tdt, tbt, 'c', 'd', tet or tf t when downl-oading data. The L9000 always transmits data with upper case letters. Another useful feature of this product is the ability to upload or downl-oad part of a data bl-ock. The questions asked prior to data transfer rload data from?' and 'Load data to?' refer to the target address of the data and NOT the location in the programmer. The first l-ocation from which to take data must be entered in response to the prompt 'Ram start?'. 14.2. InteL format There are two Intel formats supported by the L9000. The first is 'Inte1 Hex' which supports addresses up to 20 bits long and the second is rlntel 32, bit' which supports addresses up to 32 bits long. However for simplicity either format will download an Intel fi-l-e with record types 00, 01, 02, 03 or 04. However when uploading using rlntel 32 bit' a type O4 record i-s generated when the address is above FFFF. With 'InteL hex' format a type 02 record j-s generated. There are 4 types of record recogni-sed by thj-s programmer. Type O0 Data record. Type 01 End of file record. Type 02 Extended segment address record. (For 20 bit addresses). Type 04 Extended ]inear address record. (For 32 bit addresses). Each data record contains the record type, length, data l-oad address and checksum, in addition to up to 255 bytes of data. The format is specified as fol,l-ows: : NNAAAATTDD. .DDCC where is the f i-rst bvte of the record. NN is a two ascii hexadecj-mal represe.ntation of the number of data bytes. The maximum value is 255 bytes (OFFH). Note that O0 counts as zero bvtes of data. AAAA is a four ascii hexadecimaf representation of the data load address of the f j-rst byte of data. Success j-ve bytes are stored in successive locations. During loading, this address is added to the segment base address to calcul-ate the load address whj-ch is displayed. TT is a two ascii hexadecimal representation of the record type. 00 = Data. 01 = End of file. 02 = Address extension. DD..DD For type 00 data records, this is a two ascii hexadecimaL representation of each byte of data. This fiel-d is not present in end of f i-l-e records type 01. CC is a two ascii hexadecimal representation of the negatj-ve checksum of the record. Starting with the record length and ending with the checksum, the hexadecimal sum, taken two at a time, modulo 256 is 0 (2's complement). Data loading stops after reading a type 'Ol-' record. Each record is normally separated by a carriage return/linefeed. A 'Checksum errort is generated if a checksum error is found in any record. 10.3. Motorola format There are six types of record recognised by this programmer. Type 51 data record wi-th up to 32 data bytes. Address f iel-d 2 bytes. Type 32 data record with up to 32 data bytes. Address field 3 bytes. Type 53 data record with up to 32 data bytes. Address field 4 bytes. Type 37 end of file record. Address field is 4 bytes. Type SB end of file record. Address fiel-d j-s 3 bytes. Type 59 end of file record. Address fiel-d is 2 bytes. Each data record contai-ns the record type, Iength, data load address and checksum. The format is specified as foffows: STNNAA. . AADD . . DDCC is the first asci-i character in the record. T is the second ascii character in the record representi-ng the record type. L,2 or 3 = Data record. 7,8 or 9 = End of fil-e record. NN is a two ascj-i hexadecimaf representation of the record length. The record length includes the start address, data and checksum fiel,ds. The maximum number of data bytes is 25O bytes (OFFH). The maximum length is, therefore, 255 bytes incl-usive of the start address and the checksum. AA..AA is a four, six or eight ascii hexadecimal representation of the data l-oad address of the first byte of data. Successive bytes are stored i-n successive focations. During loadi-ng, this address is displayed. DD..DD is a two ascii hexadecimal representation of each byte of data. This field is not present in end of fj-Ie (types 7, B and 9 records ). CC j-s a two ascii hexadecimaf representation of the 1's complement of the eight lower order digits obtained after summing the record length, address and data bytes. Hence, the least significant byte of the sum of the record Iength, address, data bytes AND checksum will- be FFH. Data loading stops after reading a type'7', 'B'or'9'record. Record types not described above are ignored. Each record may be separated by a carriage return/Iinefeed. A 'Checksum error' is qenerated if a checksum error is found in any record. l-4.4. Binary Formats There are 3 types of binary format recogni-sed by thj-s programmer. 1. Binary (header = FF) 2. Binary (no header) 3. Dec. Bi-nary 1. Binary (header = FF) The format is specj-fied as foll-ows: HBBBB ...B8 where H is the Start of data header with binarv value 11111111 B is the Binary data 2. Binary (no header) The format is speci-fied as foll-ows: BBBB ...E}E} where B is the Binarv data 3. Dec. Binary The format is specified as follows: HH..HHLBBB ...88 where H is the Start of data header with a string of binarv val-ues 11111111 L is the end of header with binarv value O000O00O B is the Bi-narv data The binary formats carry no address information so that the first byte is assumed to be for address zero. The next byte is assumed to be byte L, etc. Binary formats can, therefore, only be used to transmit continuous blocks of data. There are also no checksums, so it is recommended that parity is enabl-ed (odd or even) when using the serial- port. The L9OOO assumes that data transmissi-on has been completed when the Iast byte of data has been read or when data transmission has stopped for at l-east five seconds. In the latter case, the address field in the display will remain unchanged for at least 5 seconds and then the checksum will- be displayed and the buzzer wil-l sound as a warning that an error might have occurred. 10. 5. Ascj-i Hex Space Format There are three types of record recognised by this programmer. Start of data marker is bvte OlH or OzH or both. Data records consist of a 2 ascii hexadecimal representation of the byte. Each pair of ascii characters is separated by a space.(20H). End of data marker j.s indicated by byte 03H. Al-1 bytes prior to the start of the data marker character are j-gnored AND al-I bytes after the end of the data marker are afso ignored. Carrj-age returns ( ODH) and/or lj-nef eeds ( OAH) are ignored , if present. If a carriage return and/or l-inefeed are present, a further space separator is not required, but it may be present. The upload record format is: * 1i 22 33 44 55 66 77 BB 99 AA BB CC DD EE FF where z * is a non printable character corresponding to byte 01H or o2H. 11 22 33 Each data byte is represented by a two ascii hexadecimal byte pair. Each byte pair must be separated by a space (2OH). For example, hexadecimal byte 2A is coded as 32H 41H _ Z is a non printable character corresponding to byte O3H. This format has no provision for transmitting address information. Up or downloading, therefore, starts at the first address and ends at the l-ast address. When uploadj-ng data, the format is as shorvn in the above example. 10.6. Tektronix Hex Format This format can only transmit data within the address range O to FFFF. For larger address ranges, use 'Extended Tektronix hexadecimal' format. The L9O0O checks that thetload data from'and'Load data to' addresses are not greater than FFFF. Un1ike Intel format, extended and normal- Tektroni-x hex formats are NOT compatible. Tektronix Hex has only one type of record with the following format: /AAAANNCCDD . . DDCS / Indicates start of record AAAA Address of first byte of data NN Record length CC A two digit hexadecimaf number. This is the sum/ modufo 256, of AAAA and NN. DD Data. Each data byte is represented by 2 ascii characters. CS Data character checksum, modulo 256. End of fj-l-e is j-ndj-cated by records wj-th a record length of O. Because of the l-imited address range, valid 'Load data from' and 'Load data to' addresses must be in the range 0 to FFFF. LO.7. Extended Tektronix Hex Format Unl-ike the normal- Tektronix hex format, this format can load data over an enormous address range from 0 to FFFFFFFFFFFFFFFF. As with most programmers, the L90OO only examines data over the address range O to FFFFFFFF. There are three types of record: Data = 6 End of file = B Symbol block= 3 (Ignored) The data record format is: SNNTCSLA. . . . . ADD Z Extended Tektronix hex record NN The number of ascii characters in the record excluding the E T Record type = 6 CS Two di-git checksum of all- characters, excJ-uding the ? and the checksum, modulo 256. L Address field length. 0 indicates 16 ascii characters. A..A Address field with variabfe length from 1 to 16 characters. DD..DD Data. Each data byte j-s represented by 2 ascii characters. The end of fil-e record is similar but the record type is B. The address field is the program starting address. There is no data. 11. PARALLEL INPUT/OUTPUT ( Centrcnics ) PORT Data can be output from or input through the Centronics port at the rear of the L9OO0. The programmer has a 36 way standard Centronics connector. As there are no supply voltages present, this port can be connected to any 'standard' Centronics printer with a ribbon cabLe. Pin 1 at one end of the cabl-e is connected to pin 1 at the other end, etc. It is, however, advisable to check that there is no confl-ict between the programmer and your printer BEFORE connecting the two products. Pi-n numbers carry the signals shown bel-ow. Note that the connector shows the pin numbers in very smal-l- numbers. The signal directj-on bel-ow is shown when the L90O0 is transmitting data. Data direction is reversed when the L9000 is receiving data.

SYSTEM MESSAGES ]-2.r Error messages A few error messages 'lock up' the programmer to avoid confusion. These are typj-caIly used when there is a danger that another message may fol-low so quickly that the original message may have been missed. Such messages are prefixed with 'E)'. These cause the current function to be aborted. The only way to return to normal- operation is to press 'CANCEL'. Messages without this prefix do not 'l-ock up' the L900O. E )Buffer o'flow The programmer has not been abl-e to process data being downloaded fast enough and a buffer has overfl-owed. Use a lower baud rate. This error is most unlikely to happen at any baud rate, even L9 ,200. Data pin o/c The device indicated by the flashing light has a faulty data bit which appears to be disconnected. Occasionally, this fault can be caused by a device which does not meet Ioh = -400 microamps. This fault can also be caused by fitting a 24 pin devj-ce i-n the top of a copy socket instead of a 28 pin device. E )Non-Asci-i char Whilst reading a record, the programmer has found a byte which is not in the range 0-9 or A-F. As this may have been a transmission error, it is worth trying agaj-n. Most MDS formats encode hex data as 2 ascii bytes. If a non-ascj-i byte is, therefore, found, the programmer knows that an error has occurred. E )RS232-Framing Whj-Ist receiving data through the RS232 port, a framing error has occurred because a valid stop bit has not been detected. Check baud rate, number of data and stop bj-ts, and parity are the same for both the programmer and the remote computer. E )RS232-Overrun Whj-lst receiving data through the RS232C port, dD extra character has been received before the programmer has been able to process the l-ast character sent. Therefore, a character has been l-ost and, hence, the function has been aborted. This should never happen unless data has been sent before the programmer is ready to receive it. Check baud rate, number of data and stop bits, and parity are the same for both the programmer and the remote computer. E )RS232-Parity Whj-lst receiving data through the RS232C port, a byte has been read with an incorrect parity bit. Check baud rate, number of data and stop bits, and parity are the same for both the programmer and the remote computer. L2.2. Warning messages W)Default paras This message may be displayed when the power is turned on. It j-ndicates that the battery backed up memory used to retain the parameters has been corrupted. The programmer will, therefore, assume default parameters. L2.3. System failure messages S)SyS.EPROM fail This message may be displayed when the power is first turned on. It indicates that there is a faul-t in the s\zstem EPROM. Do not use the instrument. S )User Ram f ail- This message may be displayed when the power is first turned on. It i-ndicates that there is a fault in the user ram. Do not use the instrument. After version 2.32 the user ram is al-so checked when the programmer is in the INITIAL state. If this message is dj-splayed the user wil-l- not be abl-e to program further devices until more data is loaded into ram. However the user would be unwise to use the programmer until the reason for the failure is found. S)Prom Vcc fail- This message means that the Vcc voltage for the devices being programmed has f al-l-en out of l-imits. The like1y cause is a f aulty eprom - try another. If this faul-t happens consistently check the hardware cal-ibration as described in Section 6.LL.2. If it stil-I fail-s there is probably a hardware fault in the programmer. S)Prom Vpp fail This message means that the Vpp voltage for the devices being programmed has fallen out of limits. The likely cause is a faulty eprom - try another. If this fault happens consistently check the hardware calibration as described in Section 6.II.2. If it stil-l fail-s there is probably a hardware fault in the programmer. L2.4. Information mgeEggeE Varj-ous messages are displayed when this programmer j-s operated. Most messages are self explanatory and are not mentioned in this section. Thj-s section includes messages which may need further explanation. Reading port - Data out of range This message can be displayed when downloading data. It is displayed because the address of the data being downloaded is not between the 'Load data from' and the 'Load data to' addresses specified before the downl-oad. Refer to section 10 for an explanation of data formats. 13. UPDATING PROGRAMMERSOFTWARE The range of devices which can be programmed by this programmer can be increased by updating the system software. Parameters, such as programmer Vcc and Vpp, are aLso controlfed by software. To update the programmer proceed as described below, but note that it is only possible to fit an eprom of a higher revision if the hardware is at the same revision level. The first digit of the serial number is the hardware revision level, e.g. the serj-al number 3-L289 has a revision l-evel of 3. The f irst digj-t of the eprom version number also def j-nes the hardware revision fevel, e.g. eprom update version 3.L4 is for hardware version 3. 1. Switch off and remove mains l-ead. 2. Turn programmer upside down with the front of the programmer facing you and remove six screws which hold the base on. Remove the base. Note that the screw nearest the supply socket is smal1er. 3. Locate the system eprom which is on the track-side of the printed circuit board and remove it. IF FITTING AN EPROM UPDATE: A Note that pin 1 is located nearest the back of the programmer when removj-ng the ol-d eprom. Make sure the pins of the new eprom are straight and then fit replacement eprom ensuring that pin 1 is nearest to the back of the programmer. Make sure that there are no bent pins. OR IF FITTING A NEW UPDATE MODULE: 4. Make sure that the pins on the new update module are straight and then fit replacement module ensuring that the edge marked "FRONT OF THE PROGRAMMER" is facing the front of thre programmer and that the arrow on the right-hand side of the modul-e is aligned with the screw on the right-hand sj-de of the pcb. The module shoul-d then easily push into the same place from where the original system eprom was removed. Make sure that there are no bent pins. TO COMPLETE ALL UPDATES: E Fit base and re-connect supply. 6. When the programmer j-s turned oo, the sign on message will be: W)Default parameters. It may be necessary to change the text/prompt language using hex key B. B. Due to the fact that we are no longer able to purchase the device originally used as our system eprom, we woufd very much appreciate its return once you are happy that the new update is working sat j-sf actorily.

The standard sockets provided on this module accommodate devices sized as foflows: Nominal- device size: 13 . B - L4.2 11.3 - l1.7mm Nominal- thickness: 2 .5 - 3. 1mm * As only two eproms can be fitted on each modu1e, it is not possible to program a 32 bj-t word in one operation. The first two eproms can be programmed by starting programming at 'Ram start' 0 and the second pair by starting at 'Ram startt Z,etc. 3. -PL490 MODULE FOR 29FXXX in TSOP * nevi-ces are programmea us.ing a technique known as 'temporary sector unprotectr . In this mode, even sectors which are protected can be programmed and erased. * After programming and verification, the device is left with exactly the same sectors protected as before programming. A ---=PL650 MODULE FOR PICS rni-s is not a gang module. There are four DIL sockets instead to cover the majority of PICs which program very quickly. For example, the 16C55 programs in about 1.5 seconds. * The L90O0 can secure a device by programming a bit in the configuration register. Secured devices can still be read but the data is scrambled. However it is possible to verify two secured devices against each other. When an attempt is made to read a secured device, the scrambled data is read into ram and the socket led flashes to warn the user the data is not valid. F pl,70o & pl,70r MODULES FOR MOTOROLA6BHC7O5CB/9 * tnese oevi-ces can only-be programmeo in grang mode. * The security/Iock bit can be automatically programmed on the CB, but the C9 does not have a security/Lock bit. This option must be sel-ected when using the SET TYPE function. * A secured 6BHC7O5CB cannot be detected by the L9O0O. * The read master function takes about 15 seconds because the device has to be read serially. (30 seconds for the C9) )k Data is programmed from ram to the corresponding eprom address in the microcontroll-er. As there are gaps in the eprom frdp, it should be noted that the program checksum may not correspond to the ram checksum. 6. PLBOO MODULE FOR WSI MAP DEVICES SUCH AS PSD3O1 * fni-s rnoaufe is onfy avai-fanfe witn four pl,CC sockets. * These devices can only be programmed in gang mode. * Data is programmed from ram to the corresponding eprom address. As there are gaps in the device map between arrays, it should be noted that the program checksum may not correspond to the ram checksum. tr The SECA bit is not included in the device check sum. * When the security bi-t j-s programmed in the ACR configuration the device will- be secured. Further device function such as Read, Verify, Bl-ank and Program wiJ-l not recognise the devi.ce. * The CMISER bit is inverted in the RAM and HEX files. The CMISER bit is not implemented in early versions of the device. )k The file generated by the WSI design program MAPLE is a standard Intel hex file and, as such, it can be, downloaded using the DOS copy command. 7. ---*rn-PLB74 and PLB74 Mk2 MODULE May 1993-a rrew version of the PLB74 module was released. The new modul-e can program the same devices as the ol-d modufe (8748/9H) and al-so the B74I/2 family. The new version is known as the PLB74 Mk2. The module can be identified by fitting it to an L9OO0 programmer and by pressing buttons B and B. The L9OOO display 874_Mk2 for the new module or 874 for the old. Software release 2.62 or l-ater must be fitted for the new modul-e. A mixture of new and old modules can be used to program B74B/9Hs. However if new and o1d modules are fitted and an attempt is made to program devices other than B74B/9H the L9000 will instruct the user to remove the old module. B. PLB75 & PLB76 MODULES FOR 8751 FAMILY * fne PLB75 and PLB76 moaufes snipped before March 1993 may not be able to program Intel B7C51FC and other FX versions as standard. Consult the factory for further information. Some wire links can be added to earlrz modules to correct this situation. x Lock bits can be programmed with software release 2.39 or l-ater. t( Before reading a device the L9000 attempts to find out whether or not there is a device in each socket. Before software version 2.7L, this test invoLved running the micro and detecting the output on the ALE fine. However this test is not 1O0E perfect because this signal is not available if the PC exceeds the maximum address of the micro. We have therefore changed the device insertion test to read the 'Intell-igent Identifier' which is avaifabfe in about 958 of cases. If a device does not have an Intelligent Identifier then the old method is used. -9. ---ElhisPLTLE MODULES FOR MOTOROLAMICROS SUCH AS 6BHC711E9 modutes is onty avaitaUte witf, two pLCC sockets. t( The PL71E does not use Motorofa's 'PROG' mode so early, ds well- as later devices, can be programmed. * The user must sel-ect which parts of the device are to be programmed.

For example, if the eprom is selected on the E9 variant, only that part wil-l- be read into ram and only the eprom will- be programmed. * Data is read and written into ram according to the memory map of each device. (See bel-ow. ) * When the config. register is erased, dD automatic erase of the eeprom is performed by the device. * When the eeprom or config. register is erased, dD automatic bl-ank check is performed afterwards ONLY on the part which has been selected, i.e. the eeprom, the config. register or both whichever is appropriate. * When the security bit is programmed in the config. register, further attempts to read, blank check or verify the device will erase the eeprom and config. register. * When the security bit is programmed in the config. register, and the eprom area is not bl-ank the device will be secured and not recognised by the programmer. Motorofa have specified the eprom must be erased before the device is used again. * When the config. register is programmed, some variants such as 6BHCBILE2 wil-I continue to read some of the config. bits as 1 ( 11111P111 ).

NEW DEVICES ARE ADDED EACH MONTH. PROGRAMMINGPARAMETER NOTES General- Fast programming j-s used for all- devices where the manufacturer's name is quoted, except for Texas 2764. This device is programmed with a 5OmS pulse and the verification, which is normally done as part of the programming cycle, is omitted because it does not work for some devices. For fast programming, Vcc is rai-sed to 6V and the typical programming time per byte is reduced to a few mS. For devj-ces such as P2764, Intel's quick pulse algorithm j-s used. Vpp and Vcc are marginally increased. The above sefections can usually be used for similar types. Always check that the programming voltage is correct. Never use fast programming settings un.l-ess the device is specified for this. Devices such as 27256 can often be programmed using a pulse length of 1O0uS with a slightly higher Vcc. These algorithms are typically known as 'Quick pulse', 'Ffashrit€', 'Quick pro' or 'Snap'. Some devices such as Texas 27COIO and 27C2LO use a two pass programming algorithm. These devj-ces are only programmed on the second pass as reguired (A/R). Some devj-ces such as Texas 27COIO are programmed with more than one byte at a time. This speeds up the programming sequence. Devices such as Texas 27C292 can be programmed and verified using the L9000. These devices use a differential ceIl construction to achieve high speed. They are ideal- replacements for bi-polar proms. However the L9O00 cannot check the erased state of these devices before attempting to program them. The bl-ank check f unction j-s af so suppressed. Devices such as Nec 27HC65 cannot distinguish an erased bit as either high or low during a normaf read or verify cycle. It is, therefore, only possible to bl-ank check or program an erased part. Intel- B7C51FC was added to the device l-ist in November 1991. PLB75 and PL876 modul-es shipped before this date require a small hardware modj-fication to accommodate this device. A11 modul-es shipped after this date can program this device. The Intel- 87C51 FX fami-ly of devj-ces added in November L992 need the same hardware modification as the B7C51FC. Hitachi 63701V and 63705V need adaptors which fit into PL3OO modul-es. Please contact Lloyd Research or your di-stributor for detail-s. Greenwich Emulator Modul-es The Greenwich emufator modules contain a ram chip and a battery. They are programmed as eproms but the illegal bit test is omi-tted. Once programmed, they behave as eproms and can, therefore, be used as a 1ow cost emul-ation system. DO NOT ATTEMPT TO PROGRAMGREENWICH NV RAMS USING THE EMULATOR SETTING BECAUSE THEY WILL BE DAMAGED. Page Mode Devices Some devices can only be programmed in page mode. Whilst this is very quick, there is sometimes a limitation on the set size which can be programmed, e.g. Atmel 29C256 can be programmed as a 2 IC set but not with 4 or B devices per set. If it is required to program a set of say 4 devices, then the ram must be split before programming. It is then necessary to program two sets with 16 bit data. Temporary Sector Unprotect Some devices such as Amd 29F4OOB/T have a temporary sector unprotect facili-ty whereby the device can be erased and programmed whilst maintaining the l-evel- of sector protection. 16. APPLICATION NOTES 1. Remote Control of L9000 General- Phil-osophy In general, remote control programs enable a piece of equipment to be driven from a remote computer, typically a PC. In many cases, remote control- is used to compensate for an inadequate keyboard and l-ittle more. The L9O0O is equipped with 31 function keys and, hence, there is little to be gained from such a facility. The approach we have taken, therefore, enabl-es the user to drive the programmer from a batch file using very simple commands. At one stroke, this provides the R & D user with the facility to download a file at the end of a compilation and to program a set of eproms. On the other hand, the Production Manager can use a batch file to set the required device type, download a particular file and then leave the programmer ready for manual use. Note that it is possible to remotely set up the L9000 to downl-oad data f or a second eprom whilst stil-l programmi-ng the f irst. When the input buffers of the L9OOO are fuIl, further downloading wj-ll- be stopped but wil-l resume after the first eprom has been verified. This application note outlines the general facifities availab.Le on the L9OO0 and gi-ves some examples. For precise detail-s of commands, the user is referred to the L9000 instruction manual. Remote Control- Commands A]1 remote control commands are straightforward ascj-i characters. When the programmer is in "Remote" mode, any character received at the control- port is examined. Unless the programmer is currently downloading data, the character is assumed to be a control instruction. There j-s a single ascii character for each of the 31 keys, e.g. the hex keys O to F are ascii characters O to F and P is used for program from ram, etc. There are a few special- commands which enabl-e the user to use a batch file rather than a programming language. These include the ability to set the device type or downl-oad format directly. There j-s also a facility to read back the message currently being displayed. A special command has been introduced to enable the keyboard to be totally disabled in case of inadvertent manual ooeration. Control- Ports The L9O0O is fitted with a serial and a high speed Centronics port. Remote controL commands are always received on whichever port is sel-ected for input. Data and/or remote control prompts are output to whichever port has been selected for output. However, it is not recommended that data or prompts are output to the Centronics port unl-ess the programmer is connected to a printer because standard PCs cannot receive data on the Centronics port. Remote Control Handshaking Remote controf commands are normally echoed back to the sending device. However, in some instances, this may be undesj-rabLe. In particular, when using the Centronics port of a PC, it is essential- to disabl-e the echo because the standard port of a PC can only transmit data. For some applications, it is desirable to know when the current instruction has finished. This j-s indicated by the L900O sending a prompt signr+tback to the host machine. If this prompt is not requj-red, it can be turned off . In some cases, dD j-nstruction may have ended in fail-ure, e.g. a device may have fai1ed to program. In this instance, the prompt '+t is changed to '-' . If the controlling machj-ne then sends a r - r to the L9OOO, the programmer sends a two line message back to the control-ler showing the appropriate error message. Both lines are prefixed with a '?'. In the case of mul-tiple errors, the L9000 always reports the first error. The act of reading the error message cfears the error buffer. Changing From "Local on]y" To "Local and remote" To "Remote only" The L9O0O always powers up in "Local only" mode. It can be switched into "Local and remote" mode by one of 3 methods:- 1. Using the "Special function" facility on the programmer; ^ 2. Sending a ' ' character to the input port. This character and al-I future control- commands are echoed back. Whenever a command string has been completed, a prompt character is transmitted; and 3. Sending a 'Z' character to the input port. This character and al-l- future control- commands are NOT echoed back. The prompt character is al-so inhibj-ted. If the Centronics port j-s selected for output, the L90O0 will not accept a remote command to switch into remote mode through the Centronics port because a printer may be connected to it. If the user switches to remote controf on the keyboard and if the Centroni-cs port is selected for input, the user must not connect a Centronics printer to the L9O00 with this configuration. The local keyboard can be disabl-ed by sending an H to the programmer when it is in remote mode at the INITIAL state. Examples: These examples assume that a PC using DOS is being used. Example 1- This first example downl-oads a file of data in Motorola hex formats over the address range O to TFFFF hex, sel-ects a device type Toshiba 571000 - and programs one device. A batch fil-e, L90O0.BAT is created using 3 commands:- REM Sets up remote control-, starts download, etc. COPY START. PRN: REM Downl-oads the data fil-e - DATA. COPY DATA.MOT PRN: REM Sets device type and starts programming. COPY END. PRN: The above example uses the Centronics port. To use the COM1 seriaf R5232 port, replace PRN by COMI: . Naturally, the L9O00 input port must be sel-ected correctfy using the SET COMMS functj-on. The fi-le START. contains the foll-owinq:- Z ;Enter remote control without echo or prompt. I , Download. MG ;Motorola format. OG ;Load from address O. The G is for ACCEPT. TFFFFG ;Load to address 7FFFF. 0G ;Load data at ram start 0. The above file would work perfectly satisfactorily but it could be presented more simply on a single fine:- Z ;Enter remote control- without echo or prompt. IMGOGTFFFFGOG ;Downfoad in Motorola format from address 0 ;to TFFFF with data loading at ram start 0. ' Note that al-l- characters after the ;' to the end of l-ine are ignored and can be used for notes. The fil-e END contains the following: EIG ;SelectR&Dmode. T"571000 Toshiba"GGllGPOG ;Devi-ce type 571O0O Toshiba with 1 IC ;per set and identifier check ; compatibl-e. ;Program from ram start O. NOTE: It is essential to have at least I space between the device type and the make. The make must have at least 3 characters. The first three characters of the make must be as used by the L9OOO. However, the characters are not case sensitive. Example 2 This example downloads an Intel hex fiLe, edits four bytes in ram (perhaps a serial number) and then starts programming a single device. The Centronics por:t is used throughout. As before, 3 fil-es are used - START.JBI, the data file, and END.JBI. A batch file, JOB1.BAT is created using 3 commands:- REM Sets up remote control, starts download, etc. COPY START.JBl PRN: REM Downfoads the data file - DATA. INT COPY DATA. INT PRN: REM Sets device type and starts programming. COPY END.JBl PRN: START. JB1 Z ;Enter remote control- without echo or prompt. IIGOGTFFFGOG ;Download, Intel- format, Load from O to TFFF ;Ram start 0. The next file to be sent is the data fi-le" Then the last command fil-e END.JBI is sent. EIG ;Sel-ect R & D mode. 11OOG44l56lc ;Change bytes 1OO and 1O1 to 44 and 56 hex. T"27c256 tex"GcllG ;Set device type to 27C256 Texas. (Lower case icharacters can be used.

Example 3 In this example, the serial port is used and it is assumed that the user has written a control program. The example shows the response of the L90OO. The application requj-res a file to be downl-oaded in Intel hex and a set of four devices - 27COIO Texas - to be programmed in 16 bit mode.

The first identifj-es the manufacturer of the eprom and the second the device type. Unfortunately, the system has not been used rigorously by the eprom manufacturers and, therefore, cannot be relied upon to set the devj-ce type, €.9. some 275I3s contain the device code for 275L2sl However,it is a useful double check. If thj-s check were to be implemented as such, it woul-d be very restrj-ctive because, oD many occasions, it j-s possible to mix different device types with different codes. Furthermore, since all eproms of a particular type are read-compatible, it would be ilIogical to insist that the master has the same programming algorithm as the copj-es. However, errors coufd occur if the master device has not been checked. The L9OOO, therefore, checks the Intelligent Identifier on two Ievefs. Intell-igent Identifier check for device size and type: Since al-l eproms of a particular type are read-compati-b1e, the following functions are al-l-owed providing that the selected type and the type being used are in the same family, say for example 27256s2 Read master or Blank check or Verify with ram. It would, therefore, be possible to have a master eprom such as Fujitsu 27C256 to program Texas 27C256s. Sj-mi1arly, it would be possJ-b1e to bl-ank check or verify any of these devj-ces on thj-s setting. Pl-ease note, however, that a few devices are specj-fied to operate at a supply voltage setting of +/- 10? and, if one of these settings is chosen, the blank check and verify will be performed at these limits. The device l-ist shows eproms with a 10? vol-tage margin. Intellioent Identifier chgek for programming compatibility: Very often it is required to program a number of devices of different makes. If, for exampfe, a test was applied for say Intel 27C256s, parts such as Atmel- 27C256 woul,d be rejected because they have a different device code. Their algorithms, however. are exactly the same and, hence, they can be programmed together. One of two methods can be chosen for testing the InteJ-1i-gent Identifier when selecting the device. If the 'Yes' option is chosen, the manufacturer and device code must be exactly correct. This ensures afternatives cannot be used. If 'Compatibl-e' j-s chosen, the L9OOO will allow any mix of devices to be programmed together providing they al-l use the same algorithm. The Intell-igent Identifier default: Whenever a new device type is chosen (including remotely), the Intelligent Identifier is set to the default condition (Yes, No or Compatible). The defaul-t condition can be set using Special Function no. 6. When the L9O0O is supplied, the default is to check the Intelligent Identifier. The default can be set for each user. Settj-ng the Intell,igent Identifier check for a particuJ-ar device: When a new device is sel-ected, the check wil-l- be set according to the default. If a change is required, the setting can be changed by answering the appropri-ate question at the end of the 'Set type' function. Please note, however, that this quest,i-on is only asked if the device is specified as having an Intelligent Identifier ( see devi-ce list ) . 16 . 3 Programmj-ng Eprom Cards The L9000 provides for two different card formats, namely MIPS A and ECS4 f ormats. Both cards look i-dentical, so the part number is the only means of telling the difference! There are several important differences between eproms and eprom cards. These differences/procedures are sometimes necessary to ensure that the cards are read and/or programmed correctly. If you require an additional- setting, contact your distributor or Lloyd Research Ltd. Where applicable, the Intelligent Identifier is checked. At a later date, the L9OOO will read a binary code from the card which confirms card size and type, etc. Unlike eproms, the L9000 programs every byte of each card. This means that a marginally programmed card can be overprogrammed to make it work correctly. (Unlike eproms, cards cannot be erased. ) Cards are always verj-fj-ed at both high and low Vcc. Master data can be ]oaded from a card or an eprom usinq a PL3O0 module, etc. Always return eprom cards to their anti-statj-c wall-ets and use sensibl-e anti-static handling precautions. Always make sure devices are fully j-nserted into their sockets. Do not withdraw them when the red 'LIVE' ]ioht is on. 16.4. Programming Lock Bits In Microcontrol-lers Version 2.39 onwards provides facilities for programming the lock bits of microcontrolfers such as the 87C51. The choice of whether or not to program these bj-ts must be made when selecting the device type using the SET TYPE function. After successfuf verification of ALL devices, the L90OO Locks all- 'Locked devices and dj-splays a message G xxxx' where xxxx is the checksum. Note that, ds each device has di-fferent data, it is possible to use the STEP keys to display the checksum of each device. As a general rul-e, the first lock bit stops further programming of the devi-ce. As the L9OO0 i-s unable to check this, no check i-s made. The second lock bit usually stops the device bei-ng read. The L90OO, therefore, attempts to verify the device after it has been locked. If the verify fails, the lock has worked and the'Locked @ xxxx'message is, therefore, displayed. If, however, the device does verify, the lock process has fail-ed so the program run ends with a message rlock fail' . Note that if the security/lock bit of the Motorola 6BHC705CB is programmed the L9000 cannot detect the device in the programming socket.
