RMINDR counts the BCD-coded minute value on the carry generated once per minute by the
RSECDR counting. This register is initialized to H'00 a STBY input or the RST bit in RTCCR1,
but not initialized by a RES input. The setting range is decimal 00 to 59.

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