ABSTRACT:
A multiplexed synchronous/asynchronous data bus uses three communications lines (T, C, R) to convey bi-directional synchronous data between two data devices at a relatively low data transfer rate. The data bus is configured as a full-duplex asynchronous data bus by communicating a false address between the two data devices on two communications lines (T, C) using the synchronous data bus, holding the two communications lines (T, C) in a logic high state for a period of time, and continuing to hold one of the two communications lines (C) in the logic high state during full-duplex asynchronous communication. Full-duplex asynchronous data can then communicated between the two data devices at a higher data transfer rate on two of the three communications lines (T, R).
