TWO-WAY COMMUNICATION CIRCUIT, TWO-WAY COMMUNICATION SYSTEM AND COMMUNICATION METHOD OF TWO-WAY COMMUNICATION CIRCUIT

摘要

PROBLEM TO BE SOLVED: To provide a two-way communication circuit capable of raising transmission efficiency, a two-way communication system and a communication method of the two-way communication circuit.;SOLUTION: The two-way communication circuit 10 is connected to one end of a cable for performing half-duplex communication. The two-way communication circuit 10 has: a register 40 for control which stores a control signal including a switching instruction signal for switching the transmitting/receiving directions; a communication controller 30 which manages timing based on the control signal stored in the register 40 for control and a transmitting/receiving circuit 20 for periodically switching the transmitting/receiving directions according to an instruction of the communication controller 30 based on the control signal.;COPYRIGHT: (C)2008,JPO&INPIT
