2. Set the “UART2 Mode Select” field to the type of IrDA
standard supported by your IrDA peripheral/device (IrDA or
ASKIR). For better transmission of data, your IrDA peripheral
device must be within a 30
o
angle and within a distance of 1
meter.
3. Set the “RxD, TxD Active” and “IR Transmission Delay” fields
appropriately.
RxD, TxD Active
The options are Hi, Lo; Lo, Hi; Lo, Lo; and Hi, Hi.
IR Transmission Delay
If this field is Enabled, transmission of data will be slower. This is
recommended when you encounter transmission problem with your
device. The options are: Enabled and Disabled.
Onboard Parallel Port
378/IRQ7, 3BC/IRQ7, 278/IRQ5 Selects the I/O address and
IRQ for the onboard parallel port.
Disabled Disables the onboard parallel port.
Parallel Port Mode
The options are SPP, EPP, ECP, ECP+EPP and PntMode. These apply
to a standard specification and will depend on the type and speed
of your device. Refer to your peripheral’s manual for the best option.
SPP
Allows normal speed operation but in one direction only.
ECP (Extended Capabilities Port)
Allows parallel port to operate in bidirectional mode and at a
speed faster than the normal mode’s data transfer rate.
EPP (Enhanced Parallel Port)
Allows bidirectional parallel port operation at maximum speed.
PntMode
Allows parallel port to operate in bipolar mode.
