TIMING APPARATUS, TIMING METHOD, AND ELECTRONIC APPLIANCE

摘要

The invention provides a timing apparatus that can generate timing information regarding a plurality of regions without performing a complex calculation that uses software and without causing a significant increase in electric current consumption. The timing apparatus includes: a lower counter that generates a count value that indicates a time in seconds; a first group of upper counters that generates a first group of count values that indicate a time in minutes, hours, days, months and years by performing a count operation in synchronization with the count operation performed by the lower counter; and a second group of upper counters that generates a second group of count values that indicate a time in minutes, hours, days, months and years by performing a count operation in synchronization with the count operation performed by the lower counter.

主权项

1. A timing apparatus comprising:
a frequency divider circuit that generates a frequency-divided clock signal by dividing an original oscillating clock signal; a lower counter that generates a count value that indicates a time in seconds by performing a count operation in synchronization with the frequency-divided clock signal generated by the frequency divider circuit; a first group of upper counters that generates a first group of count values that indicate a time in minutes, hours, days, months and years by performing a count operation in synchronization with the count operation performed by the lower counter based on a first group of initial count values; and a second group of upper counters that generates a second group of count values that indicate a time in minutes, hours, days, months and years by performing a count operation in synchronization with the count operation performed by the lower counter based on a second group of initial count values.
