Abstract
In a semiconductor integrated circuit having a power domain and a mechanism for a power supply shutoff, when a power supply to the power domain is started, if a clock for an initialization operation is supplied in a state where a voltage to the power domain is unstable, power consumption during the initialization operation increases. Thus, the clock for the initialization operation of the power domain is supplied after detecting that the voltage supplied to the power domain is stabilized.
