5. Using or not using the address match break function
6. Using or not using the watchdog function
Notes on Selection of Whether or Not to Use the Watchdog Timer:
If the check box "Debug the program using the Watchdog Timer" is selected, while the user program remains
idle the emulator is performing refresh processing (by writing to the watchdog timer start register) within the
emulator control program.
Therefore, the watchdog timer starts after the user program has stopped.
To use the watchdog timer to debug the user program, select this check box. If this check box is unselected, the
emulator may run out of control after the user program has stopped.
To debug a user system that does not use the watchdog timer, do not select this check box. If this check box is
selected, the watchdog timer starts after the user program has stopped, so that if the user program is reexecuted,
the watchdog timer underflows generating a watchdog timer interrupt or a reset.
