Bits 7 to 5 are always read as 0. A write to these bits is invalid, but the write value should always
be 0.
11.2.8
RYRCNT is a 16-bit readable/writable register used as a counter for setting and counting the
BCD-coded year value in the RTC. It counts on the carry generated once per year by the month
counter.
The setting range is decimal 0000 to 9999. The RTC will not operate normally if any other value
is set. Write processing should be performed after stopping the count with the START bit in
RCR2, or by using the carry flag.
RYRCNT is not initialized by a power-on or manual reset, or in standby mode.
