摘要：
A communication control apparatus includes a master communication control unit for performing communication control for a plurality of slave units, and an intermediate communication control unit which performs the communication control for each slave unit instead of the master communication control unit. The intermediate communication control unit includes a memory section for holding transmission data necessary for slave unit communication processing and response data, which is a response to the transmission data, a transmission/reception section for sending the transmission data and for receiving the response data, and a communication processing control section. The communication processing control sections sends the transmission data in a predetermined order to the slave unit, which writes the response data received in a predetermined order into the memory section, and notifies the master communication control unit of the completion of the communication processing by using an interruption signal when the communication processing is completed.
