Another status output from the printer, a high
indicating that the printer is out of paper. Bit 5
of the Printer Status Register reads the PE
input. Refer to Parallel Port description for
use of this pin in ECP and EPP mode.
This high active output from the printer
indicates that it has power on. Bit 4 of the
Printer Status Register reads the SLCT input.
Refer to Parallel Port description for use of this
pin in ECP and EPP mode.
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
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 active when the IDE is
enabled and the I/O address is accessing an
IDE register.
The interrupt request from a logical device or
IRQIN may be output on the IRQH signal.
Refer to the configuration registers for more
information.
If EPP or ECP Mode is enabled, this output is
pulsed low, then released to allow sharing of
interrupts.
