Data Structures
struct	CRC_HandleTypeDef
Defines
#define	__HAL_CRC_RESET_HANDLE_STATE(__HANDLE__)   ((__HANDLE__)->State = HAL_CRC_STATE_RESET)
	Resets CRC handle state.
#define	__HAL_CRC_DR_RESET(__HANDLE__)   ((__HANDLE__)->Instance->CR |= CRC_CR_RESET)
	Resets CRC Data Register.
#define	__HAL_CRC_SET_IDR(__HANDLE__, __VALUE__)   (WRITE_REG((__HANDLE__)->Instance->IDR, (__VALUE__)))
	Stores a 8-bit data in the Independent Data(ID) register.
#define	__HAL_CRC_GET_IDR(__HANDLE__)   (((__HANDLE__)->Instance->IDR) & CRC_IDR_IDR)
	Returns the 8-bit data stored in the Independent Data(ID) register.
Enumerations
enum	HAL_CRC_StateTypeDef {   HAL_CRC_STATE_RESET = 0x00U, HAL_CRC_STATE_READY = 0x01U, HAL_CRC_STATE_BUSY = 0x02U, HAL_CRC_STATE_TIMEOUT = 0x03U,   HAL_CRC_STATE_ERROR = 0x04U }
Functions
HAL_StatusTypeDef	HAL_CRC_Init (CRC_HandleTypeDef *hcrc)
	Initializes the CRC according to the specified parameters in the CRC_InitTypeDef and creates the associated handle.
HAL_StatusTypeDef	HAL_CRC_DeInit (CRC_HandleTypeDef *hcrc)
	DeInitializes the CRC peripheral.
__weak void	HAL_CRC_MspInit (CRC_HandleTypeDef *hcrc)
	Initializes the CRC MSP.
__weak void	HAL_CRC_MspDeInit (CRC_HandleTypeDef *hcrc)
	DeInitializes the CRC MSP.
uint32_t	HAL_CRC_Accumulate (CRC_HandleTypeDef *hcrc, uint32_t pBuffer[], uint32_t BufferLength)
	Computes the 32-bit CRC of 32-bit data buffer using combination of the previous CRC value and the new one.
uint32_t	HAL_CRC_Calculate (CRC_HandleTypeDef *hcrc, uint32_t pBuffer[], uint32_t BufferLength)
	Computes the 32-bit CRC of 32-bit data buffer independently of the previous CRC value.
HAL_CRC_StateTypeDef	HAL_CRC_GetState (CRC_HandleTypeDef *hcrc)
	Returns the CRC state.
