Abstract:
1. An externally configurable power-on-reset system for an integrated circuit, comprising: power-on-reset circuitry within the integrated circuit configured to receive a supply voltage and to generate a supply-good signal when the supply voltage has reached a threshold voltage level; and reset control circuitry within the integrated circuit coupled to receive the supply-good signal, coupled to a reset pin for the integrated circuit, and configured to output an internal reset control signal for the integrated circuit; wherein the reset control circuitry is further configured to rely upon the supply-good signal to generate the internal reset control signal if an external reset signal is not applied to the reset pin, and wherein the reset control circuitry is configured to rely upon the external reset signal to generate the internal reset control signal if the external reset signal is applied to the reset pin; and wherein the reset control circuitry comprises:
