PURPOSE:To prevent noise from being mis-recognized to be a clock signal by sending a data signal synchronously with the clock signal sent via a clock signal line so as to attain high speed data communication. CONSTITUTION:When a trigger signal is sent from a CPU1 to a CPU2 via a 1st trigger signal line 6, a data signal is sent from the CPU1 to the CPU2 via a 1st data signal line 3 synchronously with the clock signal. Conversely when the trigger signal 2 is sent from the CPU2 to the CPU1 via a 2nd trigger signal line 7, the data signal is sent from the CPU 2 to the CPU1 via the 2nd signal line 4 synchronously with the clock signal. |
