The circuit includes a transmitter, a receiver, a single FIFO, operatively connected to both the transmitter and the receiver, for storing both transmitted and received data at the end of a loopback test. The circuit may be part of a transceiver which may in turn be part of an infrared communications controller installed in a personal computer.
