Section 20 Realtime Clock (RTC)
20.3.18 RTC Control Register (RCR3)
RCR3 is readable/writable register that specifies enable or disable the alarm function of RYRCNT
that is the RTC's BCD-coded year-value counter. When the YENB bit of RCR3 is set to 1, the
RYRCNT value is compared with the RYRAR value.
RCR3 is initialized by a power-on reset.
Bits 6 to 0 of RCR3 are always read as 0. A write to these bits is invalid. If a value is written to
these bits, it should always be 0.
