UART on byte received interrupt
I've set up a the internal uart interrupt to fire when fifo is not empty. It works when the buffer size is default to 8 but when I increase the buffer size, the interrupt no longer fires. I see that for buffers greater than 8 bytes, the box is checked and greyed out so I am assuming that it is always active for fifos larger than 8. Am I wrong?
