This parameter can be: ENABLE or DISABLE.
Return values
 None.
Notes
 None.
20.2.9.3 SPI_TransmitCRC
Function Name
void SPI_TransmitCRC ( SPI_TypeDef * SPIx)
Function Description
Transmits the SPIx CRC value.
Parameters
 SPIx : where x can be 1, 2 or 3 to select the SPI peripheral.
Return values
 None.
Notes
 None.
20.2.9.4 SPI_GetCRC
Function Name
uint16_t SPI_GetCRC ( SPI_TypeDef * SPIx, uint8_t SPI_CRC)
Function Description
Returns the transmit or the receive CRC register value for the
specified SPI.
Parameters
 SPIx : where x can be 1, 2 or 3 to select the SPI peripheral.
 SPI_CRC : specifies the CRC register to be read. This
parameter can be one of the following values:
 SPI_CRC_Tx : Selects Tx CRC register
 SPI_CRC_Rx : Selects Rx CRC register
Return values
 The selected CRC register value..
