<p>PURPOSE:To improve the noise-proof performance of the low-frequency oscillation circuit for low power consumption which is built in a microcomputer. CONSTITUTION:This oscillation circuit is provided with a high-frequency clock generation circuit 2, a shift register 3 shifting a low-frequency signal by a clock, an AND circuit 5 for a low-frequency signal and the output of the shift register, and an OR circuit 4 for a low-frequency signal and the output of the shift register. The circuit is also provided with a flip-flop circuit 6 which is set or reset by the output of the circuits 5 and 4.</p> |
