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.
