Claim:
1. A method of data communications, comprising: transmitting a first synchronization (SYNC) code on a serial bus comprises of a clock wire and a data wire; communicating with a first device over the serial bus in accordance with a first mode of operation associated with a first protocol, after establishing synchronization with the first device in response to the first SYNC code; transmitting an unsynchronization (UNSYNC) code on the serial bus, where the UNSYNC code is configured to cause a loss of synchronization with the first device; transmitting a second SYNC code on the serial bus; and communicating with a second device over the serial bus in accordance with a second mode of operation associated with the first protocol, after establishing synchronization with the second device in response to the second SYNC code, wherein in the first mode of operation, a data word is encoded in a sequence of symbols, each symbol defining signaling state of each wire of the serial bus, and wherein a transition between each pair of consecutive symbols in the sequence of symbols causes a corresponding transition in signaling state on at least one wire of the serial bus during transmission of the pair of consecutive symbols.
