DESCRIPTION
nError
A low on this input from the printer indicates
that there is a error condition at the printer.
Bit 3 of the Printer Status register reads the
nERR input. Refer to Parallel Port
description for use of this pin in ECP and
EPP mode.
The bi-directional parallel data bus is used
to transfer information between CPU and
peripherals.
In EPP mode, this pin is pulled low to
extend the read/write command. This pin
has an internal pull-up.

This active low signal is used in both the XT
and AT mode. In the AT mode, this pin is
active when the IDE is enabled and the I/O
address is accessing 1F0H-1F7H and
3F6H-3F7H in primary address mode or
170H-177H and 376H,377H in secondary
address mode. In the XT mode, this signal
is active for accessing 320H-323H, 8 bit
programmed I/O or DMA.
This signal is active low only in the AT
mode, and when IO16CSB is also active.
The I/O addresses for which this pin reacts
are 1F0H-1F7H in primary address mode or
170H-177H in secondary address mode.
This pin is not used in XT mode.
This is the Hard Disk Chip select
corresponding to addresses 1F0H-1F7H in
primary address mode or 170H-177H in
secondary address mode in the AT mode
and addresses 320H-323H in the XT mode.
This is the Hard Disk Chip select
corresponding to 3F6H,3F7H for primary
address mode or 376H,377H for secondary
address mode in the AT mode and
addresses 3F6H,3F7H in the XT mode.
