PURPOSE:To manage control sections without increasing number of signal lines with simple software by controlling a slave side control section based on a command from a master side control section and sending/receiving a data alternately for each prescribed time at both the control sections after the end of synchronization. CONSTITUTION:The synchronization processing using a serial clock SCK is implemented in the clock synchronization serial transfer system. When the synchronization processing is finished, the processing cycle implementing data transmission reception is transited and the data transmission from a control section 10B to a control section 10A and the data transmission from the control section 10A to the control section 10B are implemented alternately for each prescribed time. Thus, while the processing of the opposite party side is managed, the transmission of a succeeding data is not required. Thus, the software managing the control sections 10A,10B is simplified and the cost of the controller is reduced. |
