4.19 SP10: IrDA
The board is prepared for an IrDA interface, but the IrDA transceiver (TFBS4652) is not mounted.
To enable the IrDA interface, mount U18 (TFBS4652) and adjust SJ2 and SJ3 (connect 2-3 pads).
See picture below for locating relevant components. The table below lists signal connections.
