This signal is active low. It is used to denote address read or
write operation.

This output shows the direction of the data transfer on the
parallel port bus. A low means an output/write condition and a
high means an input/read condition. This signal is normally a
low (output/write) unless PCD of the control register is set or if
an EPP read cycle is in progress.
