Abstract

An external reset switch having a reset circuit connected to it is provided here to reset an MCU incorporated in an electronic device in case the MCU does not work. The external reset switch produces reset orders when the MCU is out of work. Such reset orders are sent to the reset circuit which provided between the external switch and the MCU. The reset circuit includes a delay circuit and a switching circuit. The delay circuit delays the output of the reset orders to the switching circuit. The switching circuit, upon receiving the reset orders, produces a reset signal to the MCU.
