PURPOSE:To generate an interruption holding state in a device set at the interruption report side by providing a flip-flop which is controlled by an interruption generation resetting signal and an interruption factor resetting signal into said device. CONSTITUTION:A flip-flop 40 which is reset by an interruption generation resetting signal 11 and set by an interruption factor resetting signal 12 which are produced by a report side device 2 to be interrupted is set into an interrupting report side device 1. Thus the interruption reports of the device 1 having plural interruption factors are controlled by the device 2 and the interruption holding states are generated every 3-6 flip-flops of the device 1. Furthermore the interruption priority can be simply judged between the interrupting report side devices of other systems within the device 2. Thus the time loss can be reduced when the interruption priority is judged. |
