   [..]
        (+) Enable CRC AHB clock using __HAL_RCC_CRC_CLK_ENABLE();
        (+) Initialize CRC calculator
            (++) specify generating polynomial (peripheral default or non-default one)
            (++) specify initialization value (peripheral default or non-default one)
            (++) specify input data format
            (++) specify input or output data inversion mode if any
        (+) Use HAL_CRC_Accumulate() function to compute the CRC value of the
            input data buffer starting with the previously computed CRC as
            initialization value
        (+) Use HAL_CRC_Calculate() function to compute the CRC value of the
            input data buffer starting with the defined initialization value
            (default or non-default) to initiate CRC calculation
