E. Watchdog Timer Configuration
The Watchdog Timer (WDT) is used to generate a variety of output signals after a user
programmable count. The WDT is suitable for use in the prevention of system lock-up, such as
when software becomes trapped in a deadlock. Under these sorts of circumstances, the timer
will count to zero and the selected outputs will be driven.
Under normal circumstance, you will need to restart the WDT at regular intervals before the
timer counts to zero.
