HP 64783A/B Emulators for Motorola 68040, 68EC040, and 68LC040 Processors Technical Data Design, debug, and integrate real-time embedded systems Description The HP 64783A/B active probe emulators support Motorola 68040 microprocessors from 16.7 to 40 MHz operation. These emulators offer the measurement capabilities that include interpreted displays of on-chip registers, nonintrusive display of emulation memory, deep trace analyzer, and hardware break events. In addition, hardware assisted software breakpoints allow setting of breakpoints in target ROM space to simplify the debugging of ROM. Foreground and background monitors are included to make it easier to accommodate various targets.
