。[Scope of Claim for Utility Model Registration] A counter that counts the number of on/off operations of the operating switch, and a retriggerable timer that is driven each time the operating switch is operated and outputs a timeout signal after a certain period of time has passed after the operation. and an I/O interface that monitors the count value of the counter and the output of the timer, reads the count value immediately after the timeout signal is generated, and executes a self-test program corresponding to this count value. Test program startup circuit.
