Set the ADJ bit.
Wait for the 30 second adjust processing to be
completed.
If the Busy flag is "0," the 30 second adjust process is
completed.
30 Second Adjust
*2 : When using the 30 second adjust function, if the second digits are 00 to 29 seconds, adjust the second digits to 00 seconds
and when the second digits are 30 to 59 seconds, plus 1 minute to minute digit, and adjust the second digits to 00 seconds.
Clock data can adjust to the just exact time by this function with the time signal.
Precautions
The crystal oscillator can be damaged by excessive shocks.
If, the crystal oscillator stops oscillating, the clock function will stop.
If the crystal oscillator is oscillating, the Busy bit will automatically recover in 244
s,
but if oscillation stops, automatic recovery will not occur.
Therefore, in this state, there is the possibility that the Busy bit will not be able to escape the check loop and the
system will hang-up.
As a fail-safe,
when it does not escape from the loop, as between 0.5 ms to 1 ms, we recommend jump to timeout procedure, to
escape from the eternal loop to enable the processing of any errors.
