Abstract
A harmonic of a resonance frequency of an oscillator, which occurs at the initial stage of the oscillation of the oscillator, is divided to obtain a pulse to be used as a clock for the operation of a microcomputer before the oscillation is stabilized. Thus, the invention provides a clock generation circuit and a microcomputer which shorten a time period required from the application of power or the clock halt state to the start of the operation of the microcomputer.
