An electronic device includes a core circuit and a detecting circuit. The core circuit receives a first clock signal and a second clock signal that are different. The core circuit generates a first working state and a second working state respectively according to the first clock signal and the second clock signal. The detecting circuit detects a relationship between the first working state and the second working state to generate a reset signal. The reset signal is configured to reset the relationship between the first working state and the second working state to an initial corresponding relationship, and reduce an influence of electromagnetic interference on the electronic device.
