23.2.2 RTC Hours and Minutes Counter Register

The real-time clock hours and minutes counter register (HOURMIN) is used to program the hours and
minutes for the TOD clock. 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.
