20.3.14 Month Alarm Register (RMONAR)
RMONAR is an 8-bit readable/writable register used as an alarm register for the RTC's BCD-
coded month value counter, RMONCNT. When the ENB bit is set to 1, the RMONAR value is
compared with the RMONCNT value. Comparison between the counter and the alarm register is
performed for those registers among RSECAR, RMINAR, RHRAR, RWKAR, RDAYAR, and
RMONAR in which the ENB bit is set to 1, and the RCR1 alarm flag is set when the respective
values all match.
The setting range is decimal 01 to 12 + ENB bit. The RTC will not operate normally if any other
value is set.
The ENB bit in RMONAR is initialized by a power-on reset. The other fields in RMONAR are
not initialized by a power-on or manual reset.
Bits 6 and 5 are always read as 0. A write to these bits is invalid, but the write value should always
be 0.

20.3.15 Year-Alarm Register (RYRAR)
RYRAR is the alarm register for the RTC's BCD-coded year-value counter RYRCNT. When the
YENB bit of RCR3 is set to 1, the RYRCNT value is compared with the RYRAR value.
Comparison between the counter and the alarm register only takes place with the alarm registers
(RSECAR, RMINAR, RHRAR, RWKAR, RDAYAR and RMONAR) in which the ENB and
YENB bits are set to 1. The alarm flag of RCR1 is only set to 1 when the respective values all
match.
The setting range of RYRAR is decimal 0000 to 9999, and normal operation is not obtained if a
value beyond this range is set here.
