17.3.14 Month Alarm Register (RMONAR)
RMONAR is an alarm register corresponding to the 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
coincide, an alarm flag of RCR1 is set to 1.
The range of month alarm, which can be set, is 01 to 12 (decimal). Errant operation will result if
any other value is set.
The ENB bit in RMONAR is initialized by a power-on reset. The remaining RMONAR fields are
not initialized by a power-on reset or manual reset, or in standby mode.

Description
When this bit is set to 1, a comparison with the
RMONCNT value is performed.
