11.2.1.2 RTC Seconds Counter Register (SECONDS)
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. A power-on reset
(POR) sets the RTC to the reset values shown in Figure 11-3.
