FIFO READ Operation: When the FIFO is used, the first command after INT is generated is assumed to be
the FIFO READ. The first FIFO content is output immediately before the command is decoded. If this command
is not FIFO READ, the output is terminated. Using more layers of FIFO reduces the time taken to read multiple
conversion results, because the read cycle does not generate an EOC or INT, nor does it make a data
conversion. Once the FIFO is read, the entire contents in FIFO must be read out. Otherwise, the remaining data
is lost.
