  • Patent number: 9998112
    Abstract: A microcontroller is provided and includes a reset pin, a reset circuit, and a first logical circuit. A first reset signal is generated at the reset pin when the microcontroller is powered on. The reset circuit receives the first reset signal and generates a second reset signal. The reset circuit includes a plurality of flipflops. After the microcontroller is powered on, the reset circuit switches a state of the second reset signal according to the first reset signal when an output combination of a plurality of output values of the plurality of flipflops is not a specific value. The first logical circuit performs a first initialization operation when the state of the second reset signal is switched. When the second reset signal is switched, the reset circuit sets the output combination of the plurality of output values of the plurality of flipflops to the specific value.
