single word to be read after one word has been written to
an empty FIFO stack. The data is enabled on the bus at
(tWEF + tA) ns after the leading edge of W which is
known as the first write edge and remains on the bus until
the R line is raised from low to high, after which the bus
will go into a three-state mode after tRHZ ns. The EF line
will show a pulse indicating temporary reset and then will
be set. In the interval in which R is low, more words may
be written to the FIFO stack (the subsequent writes after
the first write edge will reset the Empty Flag) ; however,
the same word (written on the first write edge) presented
to the output bus as the read pointer will not be
incremented if R is low. On toggling R, the remaining
words written to the FIFO will appear on the output bus
in accordance with the read cycle timings.
In the write flow-through mode (figure 18), the FIFO
stack allows a single word of data to be written
immediately after a single word of data has been read
from a full FIFO stack. The R line causes the FF to be
reset, but the W line, being low, causes it to be set again
in anticipation of a new data word. The new word is
loaded into the FIFO stack on the leading edge of W. The
W line must be toggled when FF is not set in order to write
new data into the FIFO stack and to increment the write
pointer.
