PRINTER MODE:
FUNCTION
An active high input indicates that the printer is not ready to
receive data. Refer to the description of the parallel port for
definition of this pin in ECP and EPP mode.
EXTENSION FDD MODE: MOB2#
This pin is for Extension FDD B; its function is the same as the
MOB# pin of FDC.
EXTENSION 2FDD MODE: MOB2#
This pin is for Extension FDD A and B; its function is the same as
the MOB# pin of FDC.
PRINTER MODE: ACK#
An active low input on this pin indicates that the printer has
received data and is ready to accept more data. Refer to the
description of the parallel port for the definition of this pin in ECP
and EPP mode.
EXTENSION FDD MODE: DSB2#
This pin is for the Extension FDD B; its functions is the same as
the DSB# pin of FDC.
EXTENSION 2FDD MODE: DSB2#
This pin is for Extension FDD A and B; its function is the same as
the DSB# pin of FDC.
PRINTER MODE: PD7
Parallel port data bus bit 7. 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: DSA2#
This pin is for Extension FDD A; its function is the same as the
DSA# pin of FDC.
PRINTER MODE: PD6
Parallel port data bus bit 6. 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: MOA2#
This pin is for Extension FDD A; its function is the same as the
MOA# pin of FDC.
