<p>PROBLEM TO BE SOLVED: To provide the reset method of a CPU capable of resetting the CPU by simultaneously depressing a power supply switch and at least one more switch for more than a prescribed time. SOLUTION: In this reset method for the time when a CPU runs away and falls into a hung-up state, switch simultaneous depression time detection circuits OR and TE are provided, and when it has been detected that the power supply switch S1 and at least one more switch S2 are simultaneously pressurized for more than the prescribed time in the switch simultaneous depression time detection circuits OR and TE, reset signals/RST are outputted from the switch simultaneous depression time detection circuits OR and TE to the reset input terminal of the CPU and the CPU is reset.</p> |
