Abstract
An input/output circuit implemented in an integrated circuit is described. The input/output circuit comprises an input/output pad and a voltage control circuit coupled to the input/output pad. The voltage control circuit sets a voltage at the input/output pad at a first voltage when the input/output pad is implemented as an input pad and at a second voltage when the input/output pad is implemented as an output pad. Methods of implementing input/output circuits in an integrated circuit are also described.
