PROBLEM TO BE SOLVED: To provide a data communication system where interrupt priority of data transmission in a control section 6 of a transmission reception unit is enhanced and the function of multiple address communication can sufficiently be enhanced. SOLUTION: The data communication system uses a slot, selected from a channel selected between two selected transmission reception units to conduct data communication of the TDMA/TDD system. The transmitter side transmission reception unit uses a slot selected within one frame time after receiving supply of data from a host device to transmit data, and a receiver side transmission reception unit supplies data to the host device immediately before a lapse of one frame time, after the receipt of the data.
