1. A method of data communication operable on a transmitting device comprising:
at a first device, encoding a data word in a set of transition numbers;
at the first device, converting the set of transition numbers into a sequence of symbols, wherein timing information is encoded in transitions between symbols in the sequence of symbols; and
transmitting, from the first device, the sequence of symbols on a two-wire serial bus when the two-wire serial bus is operated in a first mode of operation, wherein each transition between consecutive symbols causes a change in a signaling state of the two-wire serial bus,
wherein the sequence of symbols is ignored by a second device coupled to the two-wire serial bus while the two-wire serial bus is in the first mode of operation, and
wherein the second device is configured for communicating on the two-wire serial bus using a second mode of operation of the two-wire serial bus.
