RTC New Year and Stopwatch Register (RTC_NY_STP) Register
Typical stopwatch operation is to write an initial value into the 8-bit wide SW_SET field and assert the
WRITE_SW bit. The WRITE_SW bit is immediately auto cleared, but it triggers the stopwatch minute
countdown to begin.
Number of minutes to be written into stopwatch. Max is 255, a little over 4 hours.
New year value to be written to the RTC current date register after successful state machine transition by
SET_DATE and PAUSE_DATE bits.
This is part of date set function in the previous register.
New date (1-31) is written in RTC current date register after state machine transition by SET_DATE and
PAUSE_DATE bits. Only the lower 5 bits of this field are used.
A date of 1 indicates the first day of the month, 2 indicates the second day of the month, 31 indicates the last
day of the month of January.
If 0 is written (not recommend), the date is set to 0 until the end of the day. The date is then incremented to 1.
YEAR_SET in the following register is also part of the date set function.
