17.3.4
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 range of hour can be set is 00 to 23 (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.
RHRCNT is not initialized by a power-on reset or manual reset, or in standby mode.
