E8a Emulator Section 6 Notes on Using the E8a Emulator
7. Debugging using the watchdog timer
When debugging the user program using the watchdog timer, click the [Debugging of program that uses WDT.]
check box in the [Firmware Location] tab of the [Emulator Setting] dialog box. By clicking this box, the E8a
emulator program refreshes the watchdog timer during program operation. If memory access is executed through
memory reference or modification, the watchdog timer will be refreshed by the E8a emulator program.
When using the actual MCU, the watchdog timer starts operating by writing to the watchdog timer start register.
However, when using this emulator, the watchdog timer starts after initiating the user program because the E8a
emulator program refreshes the watchdog timer even if a user program halts. Note that this timing will differ from
the actual operational timing.
