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 sent out immediately before the command is decoded. If this command is
not a FIFO read, the output is terminated. Using more layers of the 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 the FIFO must be read out. Otherwise, the remaining
data is lost.
