read cycle (read FIFO or read CFR) (continued)
FIFO read cycle
The first command in the active cycle after INT is generated, if the FIFO is used, is assumed as the FIFO read
command. The first FIFO content is output immediately before the command is decoded. If this command is
not a FIFO read, then the output is terminated but the first data in the FIFO is retained until a valid FIFO read
command is decoded. Use of more layers of the FIFO reduces the time taken to read multiple data. This is
because the read cycle does not generate EOC or INT nor does it carry out any conversion.
