Abstract
A microcomputer prevents an unnecessary signal from being outputted before the microcomputer is released from a reset state when the microcomputer includes a plurality of circuit blocks operating at different power source voltages. A reset signal transmitted to an input/output terminal unit of the microcomputer is generated by carrying out an OR operation between reset signals transmitted to a 3 V system circuit unit and a 5 V system circuit unit by an OR gate.
