IMPORTANT
Note on RESET* Input:
"L" level input from the user system to pin RESET* is accepted only while a user program is being
executed (only while the RUN status LED on the PC4701's front panel is lit).
Notes on Maskable Interrupts:
Even if a user program is not being executed (including when run-time debugging is being performed),
the evaluation MCU keeps running so as to control the emulation pod. If a maskable interrupt is
requested when the user program is not being executed (including when run-time debugging is being
performed), the maskable interrupt request cannot be accepted, because the emulator disables
interrupts. The interrupt request is accepted immediately after the user program execution is started.
Take note that when the user program is not being executed (including when run-time debugging is
being performed), a peripheral I/O interruption is not accepted.
Note on Final Evaluation:
Be sure to evaluate your system with an evaluation MCU. Before starting mask production, evaluate
your system and make final confirmation with a CS (Commercial Sample) version MCU.
