description "
The watchdog IO device allows applications to make use of a
timer facility. Depending on the underlying hardware device
driver, a watchdog timeout will either cause a board reset
or an action routine to be called. The application must call
the watchdog reset function at regular intervals, or else the
device will timeout. The assumption is that the watchdog timer
should never trigger unless there has been a serious fault in
either the hardware or the software."

Some watchdog devices reset the board on timeout - for these

actions so the code gets disabled when this option is set.
When this option is not set, it is the application's
responsibility to register an action handler which can force
a board reset when it gets called."
