ABSTRACT:
A circuit includes a reset circuit body and a delay circuit. The circuit body outputs a signal which indicates a reset when the supply of a supply voltage is initiated until the supply voltage reaches a sufficient value and indicates release of the reset after it reaches the sufficient value. The delay circuit outputs a signal obtained by delaying start of the indication of the release of the reset, taking into consideration of a sharp rise of the supply voltage. The reset circuit may include a circuit for eliminating a momentary change indicating the reset, and a selection circuit for selecting either an output of the delay circuit or an output of the momentary reset indication elimination circuit.
