15.3.7 Month Counter (RMONCNT)
RMONCNT is used for setting/counting in the BCD-coded month section. The count operation is
performed by a carry for each month of the date counter.
The assignable range is from 01 through 12 (practically in BCD), otherwise operation errors
occur. Carry out write processing after stopping the count operation through the setting of the
START bit in RCR2.
