Abstract
A communications bus operates using transition coding, for example NRZI coding, with transition-dominant signalling. That is, when the signal takes a first binary value, binary '1', the component drives the bus line to its opposite state, and, when the signal takes a second binary value, binary '0', the component does not actively drive the bus line. During arbitration, each arbitrating component writes a unique arbitrand onto the bus, and arbitration is lost by each component that writes a binary “0” when at least one other component writes a binary “1”. The components preferably do not use transition-dominant signalling when transmitting data payloads. For such traffic they actively drive the binary “0”s as well as binary “1”s.
