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 range of minute can be set is 00 to 59 (decimal). Errant operation will result if any other value
is set. Carry out write processing after stopping the count operation with the START bit in RCR2.
RMINCNT is not initialized by a power-on reset or manual reset, or in standby mode.
