Can anybody to help me? I try to use the pin 2.9 as RXD for the uart 2 (Lpc1769). I use Lpcopen and setup pin in function mode (2), as input and initialize at state low. I connect the data out from a rfid module but the interrupt of uart is never fired up. If i use the same rfid module and config the pin 0.11 as RXD, everything works perfectly.
