The Watchdog Timer (WDT) can be used to prevent system lock-up if the software becomes trapped in a
deadlock. It features a 12-bit down counter that allows a watchdog period of up to 16 seconds (slow clock around
32 kHz). It can generate a general reset or a processor reset only. In addition, it can be stopped while the
processor is in debug mode or idle mode.
