FUNCTION
PRINTER MODE:
An active high input on this pin indicates that the printer has
detected the end of the paper. 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: WD2#
This pin is for Extension FDD B; its function is the same as the
WD# pin of FDC.
EXTENSION 2FDD MODE: WD2#
This pin is for Extension FDD A and B; its function is the same as
the WD# pin of FDC.
PRINTER MODE:
An active high input indicates that the printer is not ready to
receive data. This pin is pulled high internally. 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. 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: 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.
