DATA COMMUNICATION METHOD, TRANSMISSION RECEPTION CIRCUIT, INFORMATION DEVICE PROVIDED WITH THE TRANSMISSION RECEPTION CIRCUIT, AND INFORMATION COMMUNICATION NETWORK

摘要

PROBLEM TO BE SOLVED: To provide a transmission reception circuit that can transmit/receive added information between nodes in the case of automatically reconfiguring a network by an added or eliminated node.;SOLUTION: The transmission reception circuit 10 is provided to a node to transmit/receive a data signal and an arbitration signal (control code) between nodes. The transmission reception circuit 10 is provided with a transmission section and a reception section. The transmission section is provided with: a PHY state machine 11 for generating a control code; a BUS_-RESET generation request generating circuit 13 that generates a BUS_-RESET generation request signal (information code); and a multiplexer 15 that selects and transmits either code of the control code and the information code under the control of the PHY state machine 11. The reception section is provided with a Dilution discrimination circuit 18 that discriminates whether the received signal is the control code or the information code.;COPYRIGHT: (C)2003,JPO
