	The watchdog device allows applications to make use of a
	timer facility. First the application should register an
	action routine with the watchdog device, and start the
	watchdog running. After this the application must call a
	watchdog reset function at regular intervals, or else the
	device will cause the installed action routine to be
	invoked. The assumption is that the watchdog timer should
	never trigger unless there has been a serious fault in
	either the hardware or the software, and the application's
	action routine should perform an appropriate reset
	operation."
