Hi all!

    Vladimir,

    Are you referring to RX_FIFO_CLEAR bit 1 in the FCR register? Setting it to 1 clears the RX_FIFO. Did you try it?

    Lalindra,


     Problem solved!
    Writing to the register needed to do through the operation "=" no "| ="
    As a result of the operation, "read - modify - write", reads the value of the register IIR, as written down in the register FCR.

    Сorrect variant:

           1.  fcrRegValue=UART_FCR_PROGRAM(rxTrigLevel, txTrigSpace, UART_DMA_MODE_1_ENABLE, 0, 1, 1);
            2. HWREG(hwAttrs->baseAddr + UART_FCR) = fcrRegValue;

    The technical documentation is information:
