Chapter 6. Constraints
(1) BRK instruction
(2) Software and hardware breaks
(3) Using multiplex bus with the PC4701L emulator
(4) Using address match interrupts
(5) Software resets
(6) Watchdog function
The BRK instruction cannot be used.
a. Do not set simultaneous software and hardware breaks.
b. Do not use software breaks for areas for which the MAP setting is EXTERNAL.
You can only use Fetch as a hardware break condition for the multiplex bus area.
a. Do not set a software break at the same address as you have set an address match interrupt.
b. Do not set a hardware break within the 4 bytes leading up to the address at which an address
match interrupt is invoked.
c. When the address at which an address match interrupt occurs is achieved by one-step
execution, the address match interrupt processing and the first command on return from
the interrupt are executed simultaneously.
Do not use software resets.
If using the watchdog function, you can only use program execution. If you want to use debugger
functions other than program execution, disable the watchdog function.
