Functions
HAL_StatusTypeDef	HAL_CRC_Init (CRC_HandleTypeDef *hcrc)

	DeInitialize the CRC peripheral.
__weak void	HAL_CRC_MspInit (CRC_HandleTypeDef *hcrc)
	Initializes the CRC MSP.
__weak void	HAL_CRC_MspDeInit (CRC_HandleTypeDef *hcrc)
	DeInitialize the CRC MSP.
uint32_t	HAL_CRC_Accumulate (CRC_HandleTypeDef *hcrc, uint32_t pBuffer[], uint32_t BufferLength)
	Compute the 7, 8, 16 or 32-bit CRC value of an 8, 16 or 32-bit data buffer starting with the previously computed CRC as initialization value.
uint32_t	HAL_CRC_Calculate (CRC_HandleTypeDef *hcrc, uint32_t pBuffer[], uint32_t BufferLength)
	Compute the 7, 8, 16 or 32-bit CRC value of an 8, 16 or 32-bit data buffer starting with hcrc->Instance->INIT as initialization value.
