FIFO data bus  
When high, do not write data into the FIFO. Whenlow,  
data can be written into the FIFO by strobing WR high,  
then low.

When high, do not read data fromthe FIFO. Whenlow,  
there is data available in the FIFO which canbe read by  
strobing RD# low, thenhigh.  
Writes the data byte on the D0...D7pins into the  
transmit FIFO bufferwhen WR goesfromhigh to low.  
Enables the current FIFO data byte on D0...D7 whenlow.  
Fetches the next FIFO data byte (if available) fromthe  
receive FIFO buffer whenRD#goesfromhigh to low
