Abstract
A processor-oriented device provides a watchdog timer having a test mode programmable reset. When the device is placed in a test mode by pulling a test mode hardware pin during a reset of the timer and then an appropriate write key is provided to the timer, a watchdog timer reset count is writeable, allowing for a programmable duration for a watchdog timer reset. The watchdog timer reset count may be a reset duration value maintained by a watchdog timer reset counter. Based on both a test mode signal from watchdog timer test mode enable logic and a write key, watchdog timer reset write enable logic enables writes to the watchdog timer reset count.
