Patent ID: 8296592

Claim:
A semiconductor integrated circuit comprising: a circuit block capable of stopping power consumption at a time of an operation-stopped state, and starting an operation and performing a specific process upon receiving a resume event signal instructing a start of an operation; a power saving control circuit that sets necessary data in the circuit block in the operation-stopped state when the resume event signal is input, the necessary data being required to resume an operation of the circuit block; a resume signal mask circuit that masks an input of the resume event signal to the circuit block during a period in which the circuit block is in the operation-stopped state and a period in which the power saving control circuit is setting the necessary data in the circuit block; a resume signal hold circuit that holds a state of the resume event signal at least until after the data has been set in the circuit block and outputs the resume event signal to the circuit block through the resume signal mask circuit if the resume event signal is input during a period in which the circuit block is in the operation-stopped state and a period in which the power saving control circuit is setting the necessary data in the circuit block.
