===============================================================================
   [..]

   (#) Enable CRC AHB clock using __HAL_RCC_CRC_CLK_ENABLE();

   (#) Initialize CRC calculator
        (++) specify generating polynomial (IP default or non-default one)
        (++) specify initialization value (IP 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
