Remarks
Stops the action regardless of the converting status.
If more than one channel are converted, the generating stops after the conversion of all channels completes when the command is executed.
When FIFO memory is used, the conversion data which have not been output are being left in the memory even if the conversion is stopped by this function. In this status when AioStartAo is executed once more, the conversion start, the data is continued to output.
This function cannot be used on devices without
the analog output function.
This function can be executed even if the device is in operation.
