Operating conditions
— Normal operation
When the time advances from 23:59 to 0:00 (0:00 a.m.), the date is advanced by 1 day.
— Current time setting mode
The clock time setting is advanced or set back in current time setting mode. If the time setting passes through
0:00 a.m. during that operation, the calendar is advanced or set back by one day.
— During calendar display
If a high level is applied to the TIME SET INPUT pin during calendar display, the date is advanced by one day,
and if a low level is applied, it is set back by one day.
Setting
— The calendar can be set during calendar display
The calendar display following initial reset, i.e., the initial value, will be January 1. the TIME SET INPUT pin
is used for setting the date.
If a high level is applied to the TIME SET INPUT pin during calendar display, the date is advanced by one day,
and if a low level is applied, it is set back by one day. In either case, if the input is applied for more than 0.5 to
1.0 seconds the setting changes at a speed of 20 msec per increment when 60 Hz is input to the 50/60 Hz
INPUT pin, and at 17 msec per increment for a 50 Hz input.
— Only the day can be changed directly using the TIME SET INPUT pin. To change the month, count either up
or down through the days of the month. For example, 1/30
→ 1/31 → 2/1, or 2/2 → 2/1 → 1/31.
— Displaying leap year’s day (2/29)
To display leap year’s day, with the calender display set to 3/1, apply a low level to the TIME SET INPUT pin
for more than 20 msec and less than 0.5 seconds, i.e., back up the date one day. In normal operation, the date
advances from 2/28 to 3/1, but in date backup, the date changes from 3/1 to 2/29 and then to 2/28.
2/27
→ 2/28 → 3/1 → 3/2..... : Normal calendar display
3/2
→ 3/1 → 2/29 → 2/28... : Display when setting the calendar in the reverse direction
