Abstract
In a security ECU, a CPU instructs a request generation circuit to generate a request signal in the normal operation mode. Thereafter, the CPU shifts from the normal operation mode to the low-power consumption mode. The request generation circuit utilizes clock signals generated by a clock signal generation circuit and continues operation even after the CPU shifts to the low-power consumption mode. Thus, the time for which the CPU operates in the normal operation mode can be reduced, and the power consumption of the entire system is thereby reduced.
