PURPOSE:To reduce the waste time in synchronism confirmation by allowing a synchronization processing part to make a check on the information of processing completion intermittently several times among plural corresponding processes in a series. CONSTITUTION:An application program 7 sends a request for n-byte transmission in response to a transmission indication from a keyboard 3 and when a rotation control part 8 finishes sending n-byte data, an end flat is set asynchronously in a circuit end information area 11. This is checked intermittently by a monitor 6 to confirm whether the flag is set or not. The contents of the rotation end information area 11 are checked at least twice. If the flag is not set in the 1st check and set before the next check, the setting of the end flag is confirmed by a monitor 6 before a wait time is elapsed. |
