RTC Hours and Minutes Counter Register (HOURMIN)
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. A power-on reset (POR) sets the RTC to the reset values shown in
