Conversion ends when any of the following factors are satisfied.
DA conversion end
Forced stop by function AioStopAo
Generating clock period error
DA conversion error
When FIFO memory is used, even if conversion is forcedly stopped by
AioStopAo function, conversion data which has not yet been output remains
in memory.
If conversion is started again with the AioStartAo function in this state,
data will be output from the subsequent data.
In any of the conversion end conditions, if conversion of multiple channels is performed, the generating at the time when the stop condition is satisfied stops after the conversion of all channels has completed.
