Figure 9-43. FIFO_DC Without Output Registers, End of Data Write Cycle
In this case, the Almost Full flag is in location 2 before the FIFO_DC is filled. The Almost Full flag is asserted when
N-2 location is written, and Full flag is asserted when the last word is written into the FIFO_DC.
Data_X data inputs do not get written as the FIFO_DC is full (Full flag is high).
Note that the assertion of these flags is immediate and there is no latency when they go true.
Now let us look at the waveforms when the contents of the FIFO_DC are read out. Figure 9-44 shows the start of
the read cycle. RdEn goes high and the data read starts. The Full and Almost Full flags get de-asserted as shown.
In this case, note that the de-assertion is delayed by two clock cycles.
