Abstract
A microcomputer in which a voltage drop in a power source is detected by a voltage detecting circuit, and a capacitor is connected to a first power source and/or a second power source on the basis of a detection signal of said detecting circuit thereby to be charged/discharged, so that a reset signal is generated. The supply of a clock signal is controlled on the basis of said detection signal. When a source voltage of the microcomputer is found to be lower than a reference voltage but recovering in a short time, it is possible to resume a programmed operation from a temporary cut-off state without initializing the program.
