PURPOSE: To reduce the communication time and to relieve the processing load for hand-shake. CONSTITUTION: A master CPU 16 and a slave CPU 26 send/receive data by using data lines B, C. A keyword for an initializing request is given to a communication message from the slave CPU 26 to the master CPU 16. The initializing request from the slave CPU 26 to the master CPU 16 is made by using the keyword on the occurrence of a communication error in the slave CPU 26. Furthermore, the master CPU 16 uses a request line D and a reply line E to initialize the slave CPU 26 to take synchronization on the occurrence of a communication error including the initializing request by the keyword and of the initializing at application of power. |
