(5) Month-End Correction
When the time data is written in the counter, its validity is checked and either invalid data or month-end
processing is performed.

*1.
Invalid data processing for the second data is performed through the carry pulse 1 second after
the completion of writing. The carry pulse is sent to the minute counter.
*2.
Write 0 or 1 into the AM/PM flag using the 12-hour display.
For the 24-hour display, 0 or 1 is neglected when writing into the AM/PM flag. When reading,
however, 0 is read during 0 to 11 o’clock, and 1 is read during 12 to 23 o’clock.
[Month-End Processing]
Non-existent days at the end of the month are automatically processed as the 1st day of the following
month. For example, April 31 is automatically set to May 1. Leap years are allso adjusted.
(6) Voltage Detector
The S-3510 series incorporates a voltage detector that performs sampling once a second for 62.5 ms.
When the supply voltage goes below the detection voltage, the BLD latch-up circuit latches “H”, and
stops sampling.
When the CS is turned to “H”, the output of the latch-up circuit is transmitted to the shift register only
when the subsequent command is the READ command.
Reading the BLD bit allows the decrease in the voltage to be monitored.
If the CS is turned to “L” after completing the read, sampling restarts. That is, once a decrease in the
voltage is detected, detection is not performed and the status is kept “H” as long as an initialization is not
performed or a READ command is not sent.
Caution The BLD flag can read 1 when the supply voltage increases and the first read is executed.
After that, however, sampling is permitted. Therefore, when the next read is performed after
sampling of the detector, the BLD flag is reset. Refer to the timing charts shown next:
