Claims

[Claims for Utility Model Registration] The interrupt request unit activated by selective activation of a plurality of interrupt request units sends an interrupt request signal to the interrupt control unit, and controls the output of the interrupt request signal. In an interrupt circuit that sequentially transmits an interrupt approval signal from the interrupt control section to each of the interrupt request sections via a daisy chain line in response to an input, A plurality of interrupt request unit units each including a request unit are formed, and each unit receives an interrupt request signal from each of the interrupt request units of the unit and transmits the interrupt request signal to the interrupt control unit. and a buffer section for sequentially transmitting an interrupt approval signal from the interrupt control section to each of the interrupt request sections of the unit via a daisy chain line.
