PRINTER MODE: INIT#
Output line for the printer initialization. This pin is pulled high
internally. Refer to the description of the parallel port for the
definition of this pin in ECP and EPP mode.
EXTENSION FDD MODE: DIR2#
This pin is for Extension FDD B; its function is the same as
the DIR# pin of FDC.
EXTENSION 2FDD MODE: DIR2#
This pin is for Extension FDD A and B; its function is the
same as the DIR# pin of FDC.
PRINTER MODE: AFD#
An active low output from this pin causes the printer to auto
feed a line after a line is printed. This pin is pulled high
internally. Refer to the description of the parallel port for the
definition of this pin in ECP and EPP mode.
EXTENSION FDD MODE: DRVDEN0
This pin is for Extension FDD B; its function is the same as
the DRVDEN0 pin of FDC.
EXTENSION 2FDD MODE: DRVDEN0
This pin is for Extension FDD A and B; its function is the
same as the DRVDEN0 pin of FDC.
PRINTER MODE: STB#
An active low output is used to latch the parallel data into the
printer. This pin is pulled high internally.
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.
