2.
Using 1Hz interrupt
can read correctly if reading data after 1Hz interrupt occurred.
Using two times reading
carries over. To ensure correct data reading, please read twice, as follows:
1Hz interrupt and the count up of internal data synchronize. Therefore, data
There is a possibility of incorrect clock data reading when the internal counter
