RTC Date Set Register (RTC_DSR)
A software sequence using the pause_date bit in conjunction with the set_date bit must be followed to load
new values into the RTC current time register
The SET_DATE bit cannot be set to 1 unless the PAUSE_DATE bit is also set to 1.
The proper software sequence is:
The MONTH_SET, WEEKDAY_SET, and the DATE_SET fields should remain consistent throughout the four
steps (i.e., at the desired new time values).
The YEAR_SET field is located in the RTC new year and stopwatch register. The month, weekday, date and
year fields 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 zero for normal operation.

bits. 1 = Monday; 7 = Sunday. Only the lower 3 bits of this field are used. If 0 is written (not recommended),
the weekday is set to 0 until the end of the day. The weekday is then incremented to 1.
