PURPOSE:To effectively respond when forced interruption is generated in an asynchronous circuit, by holding the output of a state flip-flop with an interruption state flip-flop responding to a holding timing from a holding information flip-flop sent by responding to the generation of the forced interruption. CONSTITUTION:The interruption state flip-flop 4 which inputs the output signal of the state flip-flop 3, and the holding information flip-flop 6 which sends the holding timing to the interruption state flip-flop 4 by responding to the generation of interruption in the asynchronous circuit, are provided. And by responding to the holding timing from the holding information flip-flop 6, the output signal of the state flip-flop 3 is held with the interruption state flip-flop 4 for a prescribed time. In such a way, it is possible to hold the operating state of an asynchronous signal generation circuit and an asynchronous signal 11, and to respond to the forced interruption in the asynchronous circuit. |
