PROBLEM TO BE SOLVED: To provide a semiconductor integrated circuit for necessarily executing an event even after the completion of resume setting and the cancellation of signal masking.SOLUTION: A resume signal hold circuit 110 holds an assertion of a resume signal instructed from the outside while a circuit block 101 is in a stand-by mode. A resume signal mask circuit 120 is provided between a circuit block 101 and the resume signal hold circuit 110, and masks the signals while the circuit block 101 is in the stand-by mode so that no signal can be input to the circuit block 101. A power saving control circuit 102 causes the resume signal hold circuit 110 to hold the assertion of the event signal and causes the resume signal mask circuit 120 to mask the signals while the circuit block 101 is in a stand-by mode and the resume setting of the circuit block 101 is performed. The power saving control circuit also causes the resume signal hold circuit 110 to cancel the holding of the assertion of the resume signal after the completion of the resume setting of the circuit block 101 and the cancellation of the signal masking by the resume signal mask circuit 120. |
