2.1-1 (ADJ)
The following operations are performed by setting the ADJ bit to 1.
After this bit is set to 1, the BSY bit is set to 1 for the maximum duration of 122.1s.
If the WTEN bit is 0, these adjustment operations are started after the WTEN bit is set to 1.
1) For second digits ranging from “00” to “29” seconds:
Time counters smaller than seconds are reset and second digits are set to “00”.
2) For second digits ranging from “30” to “59” seconds:
Time counters smaller than seconds are reset and second digits are set to “00”. Minute digits are incremented by 1.
