FUNCTION
PRINTER MODE: PD1
Parallel port data bus bit 1. Refer to the description of the
parallel port for the definition of this pin in ECP and EPP
mode.
EXTENSION FDD MODE: TRAK02#
This pin is for Extension FDD B; its function is the same as
the TRAK0# pin of FDC. It is pulled high internally.
EXTENSION. 2FDD MODE: TRAK02#
This pin is for Extension FDD A and B; its function is the
same as the TRAK0# pin of FDC. It is pulled high internally.
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: SLIN#
Output line for detection of printer selection. Refer to the
description of the parallel port for the definition of this pin in
ECP and EPP mode.
EXTENSION FDD MODE: STEP2#
This pin is for Extension FDD B; its function is the same as
the STEP# pin of FDC.
EXTENSION 2FDD MODE: STEP2#
This pin is for Extension FDD A and B; its function is the
same as the STEP# pin of FDC.
