FIFO data bus
fifo_txe#
1
0
When high, do not write data into the FIFO. When low,
data can be written into the FIFO by strobing WR high,
then low.
fifo_rxf#
1
0
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.
fifo_wr#
0
1
Writes the data byte on the D0...D7 pins into the
transmit FIFO buffer when WR goes from high to low.
fifo_rd#
0
1
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 RD# goes from high to low
