23.2.3 RTC Seconds Counter Register

The real-time clock seconds register (SECONDS) is used to program the seconds 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.
