<p>PURPOSE:To perform communication between a master station and a slave station without using a communication protocol, to miniaturize the slave station, and to perform data transmission with high reliability by detecting the defect of data due to discontinuity in advance. CONSTITUTION:An output means for a data synchronizing signal SYNC and a communication clock CLK to perform data transmission/reception control is provided in the master station 1, and the slave stations 2A-2C are provided means which perform the communication by synchronizing with transmission/ reception data by using the data synchronizing signal SYNC and the communication clock CLK, and discontinuity detecting means which detect the discontinuity of each line for the data synchronizing signal SYNC and the communication clock CLK. Therefore, it is possible to detect the defect of the data due to the discontinuity in advance by providing the discontinuity detecting means, and to perform the data transmission with high reliability as a result.</p> |
