Hi everyone! I am trying to implement connection between Smart Card and LPC11Uxx via USART using interrupt. Current level - get ATR. Without interrupt everything works well, but with them - everything is crashing. Here is screenshots of my code below. Maybe I don't undestand how to work with interrups? 
P.S. I already saw NXP emaples and even with them it is not so clear for me
