Abstract
A method of operating an input/output interface is described. The method comprises eliminating a current path into an output pin of an input/output interface while the input/output interface receives an operational power signal during a first mode of operation; and enabling the current path into the output pin of the input/output interface to limit a voltage magnitude externally applied to the output pin of the input/output interface during a second mode of operation.
