Abstract

MULTIPLEXED SYNCHRONOUS/ASYNCHRONOUS DATA BUS

Abstract of the Disclosure 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. Half duplex asynchronous data is applied at a higher data transfer rate to one of the three bus lines when another of the bus lines is held in a logic high state.
