Watchdog Input. If WDI remains high or low for longer than the watchdog timeout
period, the internal watchdog timer expires and the watchdog output asserts low.
The internal watchdog timer clears whenever
edge on WDI is detected. The watchdog has an initial watchdog timeout period
(35s min) after each reset event and a short timeout period (1.12s min) after the
first valid WDI transition. Floating WDI does not disable the watchdog timer
function.
