Abstract
An integrated circuit operable in a plurality of switching modes is disclosed. The integrated circuit includes a plurality of direct connectors and a programmable switch unit operable in a plurality of switching modes. The programmable switch unit has a plurality of bi-directional I/O ports selectively connected by way of programmable switch unit internal connectors. The integrated circuit also includes a programmable function unit directly connected to the programmable switch unit by way of the direct connectors. The programmable function unit is programmable configured to operate as required by a selected one of the plurality of switching modes. As required by the selected one of the plurality of switching modes, the programmable function unit directs the programmable switch unit to form internal connections using the programmable switch unit internal connectors such that the programmable switch unit passes signals between selected portions of the plurality of bi-directional I/O ports.
