RSECCNT is an 8-bit readable/writable register and not initialized by a power-on reset or manual
reset, or in standby mode.
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 range of minute can be set is 0 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.

15.3.4
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.
