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.

the check box (marked by a check mark when selected).

- When not using the address match break function,

deselect the check box (check mark cleared). In this case,

the address match interrupt can be used in the user

program.

This option can be selected or deselected only when you are

starting up the emulator debugger.

Using or not using the watchdog function

Specify whether or not to debug the program which uses the

watchdog function. When debugging the user system which

uses the watchdog function, select the check box.
