15.3.3
RMINCNT is used for setting/counting in the BCD-coded minute section. The count operation is
performed by a carry for each minute of the second counter.
The assignable range is from 00 through 59 (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.
RMINCNT is not initialized by a power-on reset or manual reset, or in deep standby and software
standby modes.
