15.3.14 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 operation
errors occur.
The ENB bit in RMONAR is initialized by a power-on reset or in deep standby mode. The other
bits are not initialized by a power-on reset or manual reset, or in deep standby and software
standby modes.
