RWKCNT is used for setting/counting day of week section. The count operation is performed by a
carry for each day of the date counter.
The assignable range is from 0 through 6 (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.
RWKCNT is not initialized by a power-on reset or manual reset, or in deep standby and software
standby modes.
