The time counter counts seconds, minutes, and hours.
The data format is BCD format (except during 12-hour mode). For example, when the "seconds" register value is
"0101 1001" it indicates 59 seconds.
Note with caution that writing non-existent time data may interfere with normal operation of the time counter.

The hour counter counts hours, and its clock mode differs according to the value of its /12,24 bit.
During 24-hour clock operation, bit 5 functions as H20 (two-digit hour display). During 12-hour clock
operation, bit 5 functions as an AM/PM indicator ("0" indicates AM and "1" indicates PM).
