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.
Counting Ten's Position of Minutes
Counts on 0 to 5 for 60-minute counting.
Counting One's Position of Minutes
Counts on 0 to 9 once per minute. When a carry is
generated, 1 is added to the ten's position.
