IR Function Duplex
This field is available when UART 2 Mode is set to either ASKIR or
HPSIR. This item enables you to determine the infrared (IR) function of
onboard infrared chip. Full-duplex means that you can transmit and
send information simultaneously. Half-duplex is the transmission of data
in both directions, but only one direction at a time.
!
The choice: Half, Full.
TX, RX inverting enable
Defines voltage level for Infrared module RxD (receive) mode and TxD
(transmit) mode. This setting has to match the requirements of infrared
module used in system.
!
The choice: No,No / No, Yes / Yes, No / Yes, Yes.
Onboard Parallel Port
This option is used to assign I/O address for onboard parallel port.
!
The choice: Disable, 3BC/IRQ7, 378/IRQ7, 278/IRQ5.
Onboard Parallel Mode
This feature enables you to set data transfer protocol for parallel port.
Normal allows data output only. Extended Capabilities Port (ECP) and
Enhanced Parallel Port (EPP) are bi-directional modes, and they allows
both data input and output. ECP and EPP modes are only supported
with EPP and ECP aware peripherals.
!
The choice: Normal, EPP, ECP, ECP/EPP.
ECP Mode Use DMA
When onboard parallel port is set to ECP mode, the parallel port has the
option to use DMA 3 or DMA 1.
!
The choice: 1, 3
Parallel Port EPP Type
This option offers users to specify Enhanced Parallel Port (EPP) specifi-
cation.
!
The choice: EPP 1.7, 1.9.
