Abstract
A multiplexed synchronous/asynchronous data bus is disclosed in which three bus lines are used to convey bidirectional synchronous data between at least two data devices at a relatively low data rate. Valid half duplex asynchronous data is applied at a higher data transfer rate to one of the three bus lines when only one of the bus lines is held in a logic high state.
