PURPOSE:To detect occurrence of a transmission error early and to attain normal reception processing even when a data is started to be received on its way by detecting the transmission error of the data based on the comparison between address information of a sender side buffer with address information of a receiver side buffer. CONSTITUTION:Since the check of a transmission data error is implemented based on both buffer address information sets of a sender side 22 and a receiver side 30, the transmission error of each data in data string comprising plural data is immediately detected by a comparator circuit 34. That is, the addresses of the sender side 24 and the receiver side 32 are compared for each data to detect an error of each data. Moreover, since a final data is surely grasped by the reception of an address signal 38, even when the reception is started on the way of a series of data, the transmission stop signal is surely sent. Thus, the occurrence of the transmission error is early detected and even when the reception is started on the way of the data, the normal reception processing is implemented. |
