N-phase polarity output pin mode multiplexer

摘要

System, methods and apparatus are described that facilitate transmission of data, particularly between two devices within an electronic apparatus. Data is selectively transmitted as N-phase polarity encoded symbols or as packets on differentially driven connectors. A desired operational mode for communicating between the two devices is determined, an encoder is selected to drive a plurality of connectors communicatively coupling the two devices, and a plurality of drivers is configured to receive encoded data from the encoder and drive the plurality of connectors. Switches may couple outputs of the selected encoder to the plurality of drivers. One or more outputs of another encoder may be caused or forced to enter a high impedance mode.

1. A data transfer method operational on at least one of two devices in a terminal, comprising:
determining a type of physical interface to be used for communicating between the two devices, wherein the type of physical interface is one of a plurality of types of physical interface supported by at least one of the two devices; selecting an encoder to generate encoded data consistent with the type of physical interface to be used for communicating between the two devices; and configuring a plurality of drivers to receive the encoded data from the encoder and to drive a plurality of connectors communicatively coupling the two devices in accordance with the type of physical interface to be used for communicating between the two devices.
