11.2.1.9 RTC Days Counter Register (DAYS)
The real-time clock days counter register (DAYS) is used to program the day for the TOD clock. When the
HOUR field of the HOURMIN register rolls over from 23 to 00, 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.
