Abstract
A method and device for encoding and transmitting a clock signal, a supply voltage and bidirectional digital data from a master circuit to a slave circuit, including the steps of: holding a first conductor at a first voltage with respect to a second conductor; periodically raising the first conductor to a second voltage with respect to the second conductor, a fixed period after a previous raising to the second voltage; holding the first conductor at the second voltage for one of a number of predetermined periods, then returning the first conductor to the first voltage, the voltage of the first conductor not falling below the first voltage; controlling the predetermined periods to each have one of a number of fixed durations, each duration having a logical significance.
