Method, apparatus and storage medium for adaptation to three-phase signal swap in a three-wire communication link between two integrated circuit devices

摘要

In particular, a system, method and apparatus for facilitating data transmission between two devices in an electronic device is described. Two integrated circuit (IC) devices can be collocated within an electronic device and communicatively coupled via a three-wire three-phase interface. A data transfer method operable on a first of two or more devices includes determining the presence of a mismatch in a three-wire communication link involving two or more wires, and the failure of the three-wire communication link. When the match is determined to affect the phase relationship between two or more signals carried on three wires, the first of the three-bit symbols encoded in the three-wire communication link signaling state transition Inverting one bit, so that inverting the first bit corrects the phase relationship between the two or more signals. Three-phase signal versions can be communicated in different phase states via each of the three wires.
