PURPOSE:To inhibit the generation of difference in delay of clock synchronizing by setting a preliminarily received clock setting data to a device clock at almost the same timing through a clock setting starting signal. CONSTITUTION:While one of data transmitters/receivers 10, 20 connected to a bus 30 is defined as a clock setting commander 10, when clocks are to be synchronized, and when a clock setting starting signal is broadcast through the bus 30 after a clock setting data is preliminarily transferred to the other commander 20 to be set, the clock setting data previously received by the commander 20 to be set is set to a device clock 21. The clock setting data is set to a device clock 11 by the clock setting commander 10 when the clock setting starting signal is broadcast. |
