Notes on Address-Match Interrupts:
To debug address-match interrupts, set a software break or hardware break at the top address of the
address-match interrupt process. If you set a software break or hardware break at an address where an
address-match interrupt occurs, the program may run out of control.
When an address at which an address-match interrupt occurs is executed in one-step mode, the program
stops after executing the first instruction after returning from the address-match interrupt processing.
Note on BRK Instruction and BRK Interrupt:
With this emulator system, a BRK interrupt by a BRK instruction is exclusively used for software
break functions. Therefore, you can not use them for your program.
Notes on Software and Hardware Breaks:
The software break generates BRK interrupts by substituting the proper instruction to the BRK
instruction "00h". Therefore, when referencing the result of a trace in bus mode, "00h" is displayed for
the instruction fetch address where a software break is set, and when referencing in disassemble mode,
"BRK" instruction is displayed.
It is not possible to use a software break and a hardware break at the same time. If doing so, it may not
operate normally.
In the area where the MAP setting is EXTERNAL, software breaks cannot be used.
Note on Stop and Wait Modes:
Do not perform step execution at addresses in the stop or wait mode. It may cause communication
errors.
Note on Watchdog Function:
The MCU's watchdog timer can be used only while programs are being executed. To use it otherwise,
disable the watchdog timer.
Note on M1 (Mode Selection Input) Pin:
As the evaluation MCU in this product and the M1 pin (pin No. 36) of the user system are not
connected, this product is not affected by the status ("H", "L" or "OPEN") of the M1 pin of the user
system. Be sure to check the status of the M1 pin when evaluating with an actual MCU.
