A self-reset key state switching method collects self-reset key signals, judges the parity of the high/low level change times of the collected key signals and determines whether the key states are switched or not.
Furthermore, when each pressing signal of the key is in a high level, the first counter is increased by 1, and when the count of the first counter is an odd number or an even number, the first counter is switched to a first state; when the count of the first counter is even or odd, the first counter is switched to a second state.

Furthermore, the pressing signal of the key is a rising edge, and when the releasing reset signal is a falling edge, the state of the key is switched from the original first state to the second state; otherwise, keeping the original state;
in the second state, when the re-pressing signal of the key is a rising edge and the loosening reset signal is a falling edge, the key state is switched from the second state to the first state; otherwise, the state is kept in the second state.
Furthermore, the pressing signal of the key is a falling edge, and when the releasing reset signal is a rising edge, the state of the key is switched from the original first state to the second state; otherwise, keeping the original state;
in the second state, when the re-pressing signal of the key is a falling edge and the loosening reset signal is a rising edge, the key state is switched from the second state to the first state; otherwise, the state is kept in the second state.
