Let us assume that we start to write into the FIFO_DC to fill it. The write operation is controlled by WrClock and
WrEn, however it takes extra RdClock cycles for de-assertion of the Empty and Almost Empty flags.
On the other hand, de-assertion of Full and Almost Full result in the reading out of the data from the FIFO_DC. It
takes extra WrClock cycles, after reading this data, for the flags to come out.
With this in mind, let us look at the FIFO_DC without output registers waveforms. Figure 10-30 shows the operation
of the FIFO_DC when it is empty and the data starts to be written into it.
Figure 10-30. FIFO_DC without Output Registers, Start of Data Write Cycle
The WrEn signal must be high to start writing into the FIFO_DC. The Empty and Almost Empty flags are high to
begin and Full and Almost full are low.
When the first data is written into the FIFO_DC, the Empty flag de-asserts (or goes low), as the FIFO_DC is no lon-
ger empty. In this figure we assume that the Almost Empty setting flag setting is 3 (address location 3). So the
Almost Empty flag is de-asserted when the third address location is filled.
Now let us assume that we continue to write into the FIFO_DC to fill it. When the FIFO_DC is filled, the Almost Full
and Full Flags are asserted. Figure 10-31 shows the behavior of these flags. In this figure the FIFO_DC depth is
'N'.
