Figure 9-42. FIFO_DC Without Output Registers, Start of Data Write Cycle
The WrEn signal has to 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 gets written into the FIFO_DC, the Empty flag de-asserts (or goes low), as the FIFO_DC is no
longer empty. In this figure we are assuming that the Almost Empty setting flag setting is 3 (address location 3). So
the Almost Empty flag gets de-asserted when the third address location gets filled.
Now let is 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 9-43 shows the behavior of these flags. In this figure we assume that FIFO_DC
depth is ‘N’.
