Watchdog Timer Configuration

The 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, the user will restart the WDT at regular intervals before the timer counts
to zero.
