The present invention provides an integrated parallel and serial programming interface that can be selected between either a parallel programming mode or a serial programming mode. The present invention provides a control logic circuit for selecting between the parallel and serial modes. The present invention also includes a parallel and serial detection circuit. The control logic sends a signal to an interface circuit that selects between a serial programming mode and a parallel programming mode based on the outputs of the parallel and serial detection circuits.
