Abstract
Embodiments are directed to apparatuses and methods involving communication between a first circuit and a second circuit over a wired-data bus. An example apparatus includes an integrated circuit (IC) chip within one of the first and second circuits and a logic circuit. The IC has a first data-communication port and a second data-communication for connection to respective first and second conductors of the wired-data bus. The logic circuit communicates a code multi-bit word out of a set of code multi-bit words over the wired-data bus by using signal transitions communicated on the first and second conductors. The code multi-bit word conveys clocked data bits indicated by the signal transitions, and information unique relative to other ones of the set of code multi-bit words by a known sequential pattern of the signal transitions defined relative to timing associated with the clocked data bits.
