ABSTRACT:
A relaying controller communicates with an external tool through a first communication path based on a first communication protocol and communicates with sub-controllers through a second communication path based on a second communication protocol, thus relaying communications between the external tool and the sub-controllers. The relaying controller includes a rewritable non-volatile memory having predetermined storage areas divided in correspondence with the sub-controllers. The relaying controller transmits, in response to a memory reading request from the sub-controller, a stored data in the corresponding storage area to the sub-controller through the second communication path, and writes, in response to a memory writing request from the sub-controller, a writing data received through the second communication path in the corresponding storage area. That is, the relaying controller executes accesses of the sub-controllers to the non-volatile memory.
