Abstract
PURPOSE:To enhance power saving effect at the time of reset, by providing two kinds of voltage decreasing means. CONSTITUTION:When a reset switch 12 is turned ON, an NMOSFET10 is turned ON, a frequency divider 2 is reset, and the output of an inverter becomes a logic 0. As a result, power is supplied to a reference oscillator 1 and the frequency divider 2 via a voltage dropping resistor 7 and the NMOSFET10, but the power is not supplied to a voltage dropping circuit 6 at the same time. A pulse motor is also stopped.
