    Hi everybody,

    STR750 UART Rx Interrupt is triggered according to RXIFLSEL register. But i can choose min 1/8 Full of FIFO. So the interrupt is triggerred if FIFO has 2 bytes.

    Is there any solution to trigger Rx interrupt while FIFO has 1 byte.

    just activate also the RX timeout interrupt. This interrupt ensures that if bytes are left in RX buffer, an RX interrupt will occur, after a specified number of bits time.

    good luck
