A software sequence using the pause time bit in conjunction with the set_time bit must be followed to load
new values into the RTC current time register (see
(RTC_CTR)”). The SET_TIME bit cannot be set to 1 unless the PAUSE_TIME bit is also set to 1.
The proper software sequence is:
1. Write register with C24HOUR_SET, MINUTE_SET, and SECOND_SET fields set to the desired values and
2. Write register with C24HOUR_SET, MINUTE_SET, and SECOND_SET fields set to the desired values and
3. Write register with C24HOUR_SET, MINUTE_SET, and SECOND_SET fields set to the desired values and
4. Write register with C24HOUR_SET, MINUTE_SET, and SECOND_SET fields set to the desired values and
At completion of step 4, the RTC current time register is updated with the new time.
The C24HOUR_SET, MINUTE_SET, and the SECOND_SET fields should remain consistent throughout the
four steps (i.e., at the desired new time values).
The hour, minute and second fields of the RTC current time register are all set at the completion of step 4 of
the previous sequence.
It is important to use
instructions such as
Used with set_time above to perform time update. Must be 0 for normal operation.
This bit determines the hour output format.
0 24-hour format.
1 12-hour format with AM/PM.
This bit does not affect time set procedure, it only affects how the hour status field is presented. The new hour
format is updated immediately in the current time register.

This field is always written with 24-Hour format, it is not affected by SLCHOUR bit above.
