Abstract
A method of performing a built in test on a watchdog circuit including a watchdog timer includes: initiating the built in test with a processor being monitored by the watchdog circuit, wherein initiating includes enabling a watchdog circuit built in test reset inhibit circuit (WD BIT reset inhibit circuit) connected between an output of an active watchdog integrated reset circuit connected to the processor and a reset input of the processor; and ceasing to provide a strobe signal to the active watchdog integrated reset circuit that resets a watchdog counter in the active watchdog integrated reset circuit, the active watchdog integrated reset circuit causing a reset of the processor via its output when the watchdog counter expires by providing a signal to a reset input of the processor.
