11.3.3
RHRDR counts the BCD-coded hour value on the carry generated once per hour by RMINDR.
The setting range is either decimal 00 to 11 or 00 to 23 by the selection of the 12/24 bit in
RTCCR1.

Description
RTC Busy
This bit is set to 1 when the RTC is updating (operating)
the values of second, minute, hour, and day-of-week data
registers. When this bit is 0, the values of second, minute,
hour, and day-of-week data registers must be adopted.
Reserved
This bit is always read as 0.
Counting Ten's Position of Hours
Counts on 0 to 2 for ten's position of hours.
Counting One's Position of Hours
Counts on 0 to 9 once per hour. When a carry is
generated, 1 is added to the ten's position.
