Abstract
Embodiments provide input/output devices having programmable logic that is programmable to operate input/output devices in one of two drive modes. In various embodiments, to operate an input/output device in a first drive mode, logic circuitry is programmable to couple a reference voltage to a gate of a transistor element of an output driver. In various embodiments, to operate an input/output device in a second drive mode, the logic circuitry is programmable to couple a bias voltage to the gate of the transistor element of the output driver. In various embodiments, the logic circuitry may also be programmable to couple one of a plurality of data inputs to the output driver to operate an input/output device in either a single-ended mode or a differential mode.
