Month Alarm Register (RMONAR)

RMONAR is an alarm register corresponding to the BCD-coded month counter RMONCNT. When the ENB bit is set to
1, a comparison with the RMONCNT value is performed. From among RSECAR/RMINAR/RHRAR/RWKAR/
RDAYAR/RMONAR/RCR3, the counter and alarm register comparison is performed only on those with ENB bits set to
1, and if each of those coincides, an alarm flag of RCR1 is set to 1.
The assignable range is from 01 through 12 + ENB bits (practically in BCD); otherwise an operation error will occur.

Year Alarm Register (RYRAR)

RYRAR is an alarm register corresponding to the BCD-coded year counter RYRCNT. The assignable range is from 0000
through 9999 (practically in BCD); otherwise an operation error will occur.
