35
is Sharp's infrared communication protocol with a maximum baud rate up to
57.6K bps.
RxD; TxD Active (Hi, Lo)
This field enables you to set the IR reception/transmission polarity as High or
Low.
IR Transmission Delay (Enabled)
This field enables you to set the whether the IR transmission rate will be de-
layed while converting to receiving mode.
UR2 Duplex Mode (Half)
This field is available when UART 2 Mode is set to either ASKIR or IrDA. This
item enables you to determine the infrared function of the onboard infrared
chip. The options are Full and Half (default).
Full-duplex means that you can transmit and send information simultaneously.
Half-duplex is the transmission of data in both directions, but only one direc-
tion at a time.
Use IR Pins (IR -Rx2Tx2)
Please consule your IR peripheral documentation to select the correct setting
of the TxD and RxD signals.
Onboard Parallel Port (378/IRQ7)
This option is used to assign the I/O address and interrupt request (IRQ) for
the onboard parallel port.
Parallel Port Mode (ECP)
Enables you to set the data transfer protocol for your parallel port. There are
four options: SPP (Standard Parallel Port), EPP (Enhanced Parallel Port),
ECP (Extended Capabilities Port), and ECP+EPP.
SPP allows data output only. Extended Capabilities Port (ECP) and Enhanced
Parallel Port (EPP) are bi-directional modes, allowing both data input and output.
ECP and EPP modes are only supported with EPP- and ECP-aware peripherals.
EPP Mode Select (EPP 1.7)
The onboard parallel port is EPP spec. compliant, after you choose the on-
board parallel port with EPP function. Set the EPP version to 1.7 spec or 1.9
spec.
ECP Mode Use DMA (3)
When the onboard parallel port is set to ECP mode, the parallel port can use
DMA 3 or DMA 1.
