Table 3.10 - Synchronous FIFO Mode Read and Write Cycle Timing
In synchronous mode data can be transmitted to and from the FIFO module on each clock edge. An
external device synchronises to the CLKOUT output and it also has access to the output enable OE# input
to control data flow. An external device should drive output enable OE# low before pulling RD# line
down.
When bursts of data are to be read from the module RD# should be kept low. RXF# remains low when
there is still data to be read. Similarly when bursts of data are to be written to the module WR# should
be kept low. TXE# remains low when there is still space available for the data to be written
