-  * @brief   CRC HAL module driver.

-  *          This file provides firmware functions to manage the following

-  *          functionalities of the Cyclic Redundancy Check (CRC) peripheral:

-  *           + Initialization and de-initialization functions

-  *           + Peripheral Control functions

-  *           + Peripheral State functions

- ===============================================================================

-    [..]

-         (+) 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
