RHRCNT is used for setting/counting in the BCD-coded hour section. The count operation is
performed by a carry for each 1 hour of the minute counter.
The assignable range is from 00 through 23 (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.
RHRCNT is not initialized by a power-on reset or manual reset, or in deep standby and software
standby modes.
