ABSTRACT:
A data transfer system including a data transmission unit and a data reception unit, the data transmission unit including an arithmetic unit which, when accepting an interruption during data transfer, suspends processing in execution and immediately switches to a mode for executing the interruption processing, and the data reception unit including a received data accepting unit for temporarily accumulating received data, a data storage unit for receiving and storing received data accumulated at the received data accepting unit after the data transfer processing is completed, and a transfer control unit for inhibiting processing of shifting received data accumulated at the received data accepting unit to the data storage unit when detecting suspension of the data transfer processing due to generation of an interruption at the data transmission unit.
