In FIFO (First In First Out) type, the conversion data is always written in memory after the latest data, and is always output the oldest data from memory.
As more data than the memory capacity is added, error is returned by function AioSetAoSamplingData. But, even if error occurs by the function, it does not affect the conversion operation. If during the conversion, output data will continue outputting.
In FIFO type, data can be added during DA conversion. By writing data regularly so that the output data will not be empty, it is possible to perform sampling for a long time than the memory capacity.
