11.3.3
RHRDR counts the BCD-coded hour value on the carry generated once per hour by RMINDR.
This register is initialized to H'00 by a STBY input or the RST bit in RTCCR1, but not initialized
by a RES input. The setting range is either decimal 0 to 11 or 0 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.
