*Time Setting Input:
There are two setting inputs for use with “hour” and “minute”. Time content settings show in Table2 are
possible by activating VSS to these pins, A pull-down resistor is built-in.

Functions
Time
Hour
Immediately adds 1 to hour digits and then assigns an additional 1, at a
speed of 2 Hz, after each 1/4 to 3/4 second.
Min
Immediately adds 1 to minute digits and then assigns an additional 1, at a
speed of 2 Hz, after each 1/4 to 3/4 second. Seconds are rest.
Both
Operates both as outline above.
Second
Hour (note1) Second digits are cleared to [00].
(Alarm & Sleep)
Min
Time holds.
Both (note2) Resets hour and minute digits as [0:00] when operating in 24-H mode or
[12:00] when operating in 12-H mode.
Alarm
Hour
Immediately adds 1 to hour digits and then assigns an additional 1, at a
speed of 2 Hz, after each 1/4 to 3/4 second.
Min
Immediately adds 1 to minute digits and then assigns an additional 1, at a
speed of 2 Hz, after each 1/4 to 3/4 second.
Both
Resets hour and minute digits as [0:00] when operating in 24-hour mode or
[12:00] when operating in 12-hour mode.
Sleep
-
Sets sleep counter to [0:59] instantly when VDD is activated to sleep select
Hour
Sets Sleep counter to [1:59] instantly when VDD is activated to sleep select
and hour at the same time.
Min
Sleep counter looses 1 at a speed of 2 Hz.
Both
Sleep counter looses 1 at a speed of 2 Hz.
Note:1.Once conditions have been switched to reset or hold, input of other functions is locked until both Hour and
Min input have been separated.
2.When the digital reading for seconds is between 30 and 59 seconds, 1 is added to the digits for minutes as
he digital reading for seconds rests to [00].
*12/24H Select Input :
When this pin set open (VDD), a 12-hour display is enabled whereas connecting this pin to VSS enables
the 24-hour display. A pull-down resistor is build-in.
*Power Failure Detection Display :
