Peripheral Control functions.

  ==============================================================================
                      ##### Peripheral Control functions #####
  ==============================================================================  
    [..]  This section provides functions allowing to:
      (+) Compute the 32-bit CRC value of 32-bit data buffer,
          using combination of the previous CRC value and the new one.
      (+) Compute the 32-bit CRC value of 32-bit data buffer,
          independently of the previous CRC value.

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.

Parameters:

hcrc	pointer to a CRC_HandleTypeDef structure that contains the configuration information for CRC
pBuffer	pointer to the buffer containing the data to be computed
BufferLength	length of the buffer to be computed

Return values:

32-bit
