Î

Normal D

EFAULT

The normal parallel port mode is the standard mode

for parallel port operation.

Î

ECP Parallel port outputs are 8-bits long. Inputs are

accomplished by reading 4 of the 8 bits on the

status register.

Î

EPP The parallel port operates in the enhanced parallel

port mode (EPP). The EPP mode supports

bi-directional communication between the system

and the parallel port device and the transmission

rates between the two are much faster than the

Normal mode.

Î

ECP+EPP

The parallel port operates in the extended

capabilities port (ECP) mode. The ECP mode

supports bi-directional communication between the

system and the parallel port device and the

transmission rates between the two are much faster

than the Normal mode

The parallel port is also be compatible with EPP

devices described above

Î Parallel Port IRQ [IRQ7]

Use the Parallel Port IRQ selection to set the parallel port interrupt address.

Î

IRQ5

IRQ5 is assigned as the parallel port interrupt address

Î

IRQ7 D

EFAULT

IRQ7 is assigned as the parallel port interrupt address

Î Serial Port1 Address [3F8/IRQ4]

Î

Disabled

No base address is assigned to Serial Port 1

Î

3F8/IRQ4 D

EFAULT

I/O port address is 3F8 and the interrupt address is IRQ4
