FUNCTION
PRINTER MODE: STB#
An active low output is used to latch the parallel data into the
printer. Refer to the description of the parallel port for the definition
of this pin in ECP and EPP mode.
EXTENSION FDD MODE: This pin is a tri-state output.
EXTENSION 2FDD MODE: This pin is a tri-state output.
PRINTER MODE: PD0
Parallel port data bus bit 0. Refer to the description of the parallel
port for the definition of this pin in ECP and EPP mode.
EXTENSION FDD MODE: INDEX2#
This pin is for Extension FDD B; its function is the same as the
INDEX# pin of FDC. It is pulled high internally.
EXTENSION 2FDD MODE: INDEX2#
This pin is for Extension FDD A and B; its function is the same as
the INDEX# pin of FDC. It is pulled high internally.
PRINTER MODE: PD1
