RTC Days Counter Register (RTC_DAYS)
The RTC_DAYS register programs the day for the TOD clock. When the RTC_HOURMIN[HOUR] field
rolls over from 23 to 0, the day counter increments. It can be read or written at any time. After a write, the
time changes to the new value. This register cannot be reset because the real-time clock is always enabled
at reset. Only 16-bit accesses to this register are allowed.
25.3.10 RTC Day Alarm Register (RTC_ALRM_DAY)
The RTC_ALRM_DAY register configures the day for the alarm. The alarm settings can be read or written
at any time.

Stopwatch count. Contains the stopwatch countdown value plus one minute. Stopwatch counter decrements by the
minute (MIN) tick output from the RTC_HOURMIN register, so the average tolerance of the count is 0.5 minutes.
For better accuracy, enable the stopwatch by polling the RTC_ISR[MIN] bit or via the minute interrupt service
routine.
Note: Write the value of one less than the desired stopwatch timeout.
