void CRC_DeInit (void)
 Deinitializes CRC peripheral registers to their default reset values. More...
void CRC_ResetDR (void)
 Resets the CRC calculation unit and sets INIT register content in DR register. More...
void CRC_PolynomialSizeSelect (uint32_t CRC_PolSize)
 Selects the polynomial size. More...
void CRC_ReverseInputDataSelect (uint32_t CRC_ReverseInputData)
 Selects the reverse operation to be performed on input data. More...
void CRC_ReverseOutputDataCmd (FunctionalState NewState)

uint32_t CRC_CalcCRC (uint32_t CRC_Data)
 Computes the 32-bit CRC of a given data word(32-bit). More...
uint32_t CRC_CalcCRC16bits (uint16_t CRC_Data)
 Computes the 16-bit CRC of a given 16-bit data. More...
uint32_t CRC_CalcCRC8bits (uint8_t CRC_Data)
 Computes the 8-bit CRC of a given 8-bit data. More...
uint32_t CRC_CalcBlockCRC (uint32_t pBuffer[], uint32_t BufferLength)
 Computes the 32-bit CRC of a given buffer of data word(32-bit). More...
uint32_t CRC_GetCRC (void)
 Returns the current CRC value. More...
void CRC_SetIDRegister (uint8_t CRC_IDValue)
 Stores an 8-bit data in the Independent Data(ID) register. More...
uint8_t CRC_GetIDRegister (void)
