Abstract
A communication circuit including a first coupler, a transmission-data change detector configured to detect a change in transmission data input to a transmitter, and a received-data change detector configured to detect a change in received data output from a receiver. In a standby state in which the received-data change detector and the transmission-data change detector do not detect changes in the received data and the transmission data, an input side of the receiver is connected to the first coupler and an output side of the receiver is disconnected from the first port in a receiving path; and an input side of the transmitter is connected to the first port and an output side of the transmitter is disconnected from the first coupler in a transmitting path.
