Microchip watchdog
WebJul 31, 2024 · Simply put, the watchdog timer is a hardware timer in the PIC that, if not constantly reset by the software, will cause the PIC to reset. This feature can be incredibly useful if the PIC should hang due to a hardware or software issue and guarantees that the PIC will restart from the beginning. WebThe watchdog timer value is refreshed using the MSS_WD_reload() function. The value reloaded into the watchdog timer down counter is the value specified earlier as a parameter to the MSS_WD_init() function. Interrupt control The watchdog timer can generate interrupts instead of resetting the system when its down counter timer expires. The
