UART2 Mode Select
The system board supports IrDA function for wireless connectivity

1. Connect your IrDA cable to connector J9 on the system
board.
2. Set the “UART2 Mode Select” field to the type of IrDA
standard supported by your IrDA peripheral/device. For better
transmission of data, your IrDA peripheral device must be
within a 30
o
angle and within a distance of 1 meter.

Mode” and “Use IR Pins” fields appropriately.
