Section 14 Realtime Clock (RTC)
14.3.2
RSECCNT is used for setting/counting in the BCD-coded second section. The count operation is
performed by a carry for each second of the 64-Hz counter.
The assignable range is from 00 through 59 (practically in BCD), otherwise operation errors
occur. Carry out write processing after stopping the count operation through the setting of the
START bit in RCR2.

This bit is always read as 0. The write value should
always be 0.
Counting Ten's Position of Seconds
Counts on 0 to 5 for 60-seconds 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.
