I have a problem finding information how to receive interrupt when the RX-FIFO in the Flexcomm module is partly filled. When the configured limit in the FIFO is reached, fine, but what if it is not reached. We have experience form the LPC24xx and LPC40xx peripherals where an interrupt is triggered as soon as the flow stopps and the remaining bytes in RX-FIFO can be read out. I have seen solutions with a separate timer but is this the only solution, really? I hope we miss something important!
