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.
