16.1.4
An attempt to write to the RTCEN bit while
RTCWREN = 0 will be ignored. RTCWREN must be
set before a write to RTCEN can take place.
Like the RTCEN bit, the RTCVALH<15:8> and
RTCVALL<7:0> registers can only be written to when
RTCWREN = 1. A write to these registers, while
RTCWREN = 0, will be ignored.

The register interface for the RTCC and alarm values is
implemented using the Binary Coded Decimal (BCD)
format. This simplifies the firmware, when using the
module, as each of the digits is contained within its own
4-bit value (see Figure 16-2 and Figure 16-3).
