Abstract:
An integrated circuit device includes a pad adapted to receive a signal from an external driver. A state register is programmed with a state that indicates a voltage level to set for the pad during initialization of circuitry on the integrated circuit device responsive to the state for the pad. The voltage level may correspond to a logic low level or a logic high level. A voltage holding circuit is coupled to the pad and the state register, and is configured to force the pad to the voltage level in response to an event that causes the initialization.
