Abstract:
A clock generation device measures a frequency ratio between a clock signal CK1 (32.768 kHz+α) and a reference frequency value based on a clock signal CK3 (25 MHz), generates a clock signal CK2 obtained by masking at least one clock pulse of the clock signal CK1 based on the measurement result of the frequency ratio, and controls the measurement interval of the frequency ratio based on the difference between the measurement result of the frequency ratio and an average value of N (N is a natural number) measurement results of the frequency ratio.
