Abstract
To provide a semiconductor circuit device including a synchronous frequency divider which counts input clock signals and outputs a counted value, a selector circuit which receives signals of bits of the counted value output from the synchronous frequency divider and outputs a carry look-ahead signal of predetermined bits as an operation-processing effective-state signal in accordance with a selector signal, and an integrated circuit portion which uses a clock signal input to the synchronous frequency divider as a source clock and whose operating frequency is switched in accordance with the operation-processing effective-state signal.
