3.6 Parallel FIFO Interface-Asynchronous Mode
The Parallel FIFO Asynchronous mode is functionally the same as the Parallel FIFO Interface present in
VDIP2 has an eight bit data bus, individual read and write strobes and two hardware flow control signals.
3.6.1 Signal Description - Parallel FIFO Interface
The Parallel FIFO Interface signals can be programmed to a choice of available I/O pins.
shows the Parallel FIFO Interface signals and the pins that they can be mapped.

When high, do not read data
from the FIFO. When low, there
is data available in the FIFO
which can be read by strobing
RD# low, then high.
When high, do not write data into
the FIFO. When low, data can be
written into the FIFO by strobing
fifo_wr# high, then low.
Enables the current FIFO data
byte on D0...D7 when low.
Fetches the next FIFO data byte
(if available) from the receive
FIFO buffer when fifo_rd# goes
from high to low
Writes the data byte on the
D0...D7 pins into the transmit
FIFO buffer when fifo_wr# goes
from high to low.
