Abstract

PURPOSE:To improve the processing efficiency, by making it possible that designated optional data communication processing devices receive an operation command simultaneously by receiving a multiple address set command and communication control data from a control line and a data line respectively in the multidata communication system. CONSTITUTION:When a broadcast set command is given to control lines 109- 112 for the purpose of transferring data from the transmission side of one data communication processing device to the receiving side of other plural data communication processing devices, the multiple address set command is received by a decoder 12 in the receiving side to output a high level 1 to an output line 201. The output of this high level 1 is given to a discriminated circuit 13 to discriminate the acceptance of multiple address set. The discrimination output is given to a flip flop 14 to set the acceptance of multiple address set. The operation command following the multiple address set command from the data communication processing device in the transmission side is received by a command receiving part 11 only in data communication processing devices where the multiple address set command is received, and the received command is executed in a command processing part 15.
