 ===============================================================================
    [..]  This section provides functions allowing to:
      (+) compute the 32-bit CRC value of a 32-bit data buffer
          using combination of the previous CRC value and the new one.

       [..]  or

      (+) compute the 32-bit CRC value of a 32-bit data buffer
          independently of the previous CRC value.

uint32_t HAL_CRC_Accumulate	(	CRC_HandleTypeDef *	hcrc,
		uint32_t	pBuffer[],
		uint32_t	BufferLength
	)

Compute the 32-bit CRC value of a 32-bit data buffer starting with the previously computed CRC as initialization value.

Parameters:

hcrc	CRC handle
pBuffer	pointer to the input data buffer.
BufferLength	input data buffer length (number of uint32_t words).

Return values:

uint32_t

CRC (returned value LSBs for CRC shorter than 32 bits)

Parameters:

hcrc	CRC handle
