Abstract
A programmable input/output circuit includes a programmable output circuit configured to drive an output signal to an input/output pad at a plurality of voltages, at least one of the plurality of voltages being supplied by an external circuit. The programmable input/output circuit further includes a programmable input configured to detect an input signal from the input/output pad at the plurality of voltages. The voltage levels of the input and output circuits may be independently and dynamically controllable.
