Abstract

PURPOSE:To perform transfer which does not generate contradiction, by providing check means for normalcy of information transfer in the transmission unit and the receiving unit respectively and by detecting anomaly for transfer by the transmission unit to re-transmit information. CONSTITUTION:The transmission unit transfers information according to the instruction of central control unit CPUO; and when tansfer is completed, contents of information transfer normalcy check circuit CHK1 in the receiving unit are sent to information transfer normalcy check circuit CHKO in the transmission unit. Next, CPUO reads contents of check circuit CHKO, and CPUO causes the transmission unit to add re-transmission indication to information and re-transmit information if contents of circuit CHKO indicate anomaly of transfer control. Meanwhile, CPU1 reads contents of check circuit CHK1, and ignores received information to wait for re-transmission information with re-transmission indication added if contents of circuit CHK1 indicate anomaly. Thus, contradiction to process to same information twice in the receiving unit can be prevented.
