ABSTRACT:
Mechanisms for configuring an integrated circuit to select one of multiple external device interfaces at a time to use during communication with external devices. The integrated circuit includes a control mechanism, a selection mechanism, and a plurality of external device interfaces. The plurality of device interfaces allow the integrated circuit to communicate with various external devices that support different communication protocols. The control mechanism is configured to designate the selection of one of the plurality of device interfaces for use in communicating with an external device. The control mechanism makes use of the selection mechanism to select the designated device interface to communicate with using the communication protocol supported by the selected interface. The communication may be receiving data from the interface or providing data to the interface. Non-selected interfaces are put in an inactive state.
