Abstract
The present invention provides a programmable pin that may be selectively configured to operate as a signal pin or a power pin. A programmable pin provides increased flexibility in the design of integrated circuit devices. Programmable pins may also be used to provide better performance of the entire integrated circuit device and reduce noise in the pins of the integrated circuit device that are signal pins. The programmable pin may also include the function of retaining the last asserted state on the pin. Memory provides further functionality and flexibility in the design of integrated circuit devices.
