EFFICIENT FAST LINK TURNAROUND PROCEDURE

摘要

System, methods and apparatus are described that support multimode operation of a data communication interface. A method performed in a device coupled to a multi-wire bus includes configuring a bus interface to drive the multi-wire bus in a high-speed mode, transmitting a plurality of symbols over the multi-wire bus while the bus interface is configured to drive the multi-wire bus in the high-speed mode, providing a control sequence of symbols in the plurality of symbols, and configuring the bus interface to operate as a receiver in the high-speed mode when the control code comprises a turnaround code. The first data may be encoded in the plurality of symbols. The control sequence of symbols may include a control code that is transmitted between two synchronizing sequences of symbols.
