Appendix A Using H/W Watchdog Timer
Watchdog timer (WDT) is a hardware mechanism to secure the normal operation of a
system. When watchdog timer is set, user’s program must periodically reset the timer in
prior to watchdog timer is expired. This function allows users to reset the system in case of
system or application halts.
On Nuvo-2000+, watchdog timer function is implemented using ITE8783 Super I/O chip.
