ABSTRACT:
A plurality of switch circuits are disposed so as to correspond to a plurality of circuit blocks, respectively. Each of the plurality of switch circuits is connected between a power supply terminal of a corresponding circuit block and a power supply line. A setting circuit is disposed to set each of the plurality of switch circuits to be in a valid or invalid state. A switch control circuit turns on each of the plurality of switch circuits according to a first control signal for indicating an operation state of the plurality of circuit blocks when each of the plurality of switch circuits is set in a valid state by the setting circuit and turns on each of the plurality of switch circuits regardless of the first control signal when each of the plurality of switch circuits is set in an invalid state by the setting circuit.
