Abstract
Circuitry for testing a power-on-reset circuit in an integrated circuit includes a high-voltage detector coupled to a first I/O pad of the integrated circuit. A power-on-reset circuit in the integrated circuit has an output coupled to a driver circuit that is powered by the high-voltage. A second I/O pad of the integrated circuit is coupled to the output of the driver circuit. The driver circuit may be enabled by a signal provided on a third I/O pad of the integrated circuit.
