LL_SPI_DisableCRC()

__STATIC_INLINE void LL_SPI_DisableCRC

(

SPI_TypeDef *

SPIx

)

Disable CRC.

Note

This bit should be written only when SPI is disabled (SPE = 0) for correct operation. @rmtoll CR1 CRCEN LL_SPI_DisableCRC

Parameters

SPIx	SPI Instance

Return values

None

Definition at line 600 of file stm32f4xx_ll_spi.h.

LL_SPI_EnableCRC()

__STATIC_INLINE void LL_SPI_EnableCRC

(

SPI_TypeDef *

SPIx

)

Enable CRC.

Note

This bit should be written only when SPI is disabled (SPE = 0) for correct operation. @rmtoll CR1 CRCEN LL_SPI_EnableCRC

Parameters

SPIx	SPI Instance

Return values

None

Definition at line 588 of file stm32f4xx_ll_spi.h.

LL_SPI_IsEnabledCRC()

__STATIC_INLINE uint32_t LL_SPI_IsEnabledCRC

(

const SPI_TypeDef *

SPIx

)

Check if CRC is enabled.

Note

This bit should be written only when SPI is disabled (SPE = 0) for correct operation. @rmtoll CR1 CRCEN LL_SPI_IsEnabledCRC

Parameters

SPIx	SPI Instance

Return values

State

of bit (1 or 0).

LL_SPI_SetCRCNext()

__STATIC_INLINE void LL_SPI_SetCRCNext

(

SPI_TypeDef *

SPIx

)

Set CRCNext to transfer CRC on the line.

Note

This bit has to be written as soon as the last data is written in the SPIx_DR register. @rmtoll CR1 CRCNEXT LL_SPI_SetCRCNext

Parameters

SPIx	SPI Instance

Return values

None

Definition at line 624 of file stm32f4xx_ll_spi.h.

__STATIC_INLINE void LL_SPI_SetCRCPolynomial	(	SPI_TypeDef *	SPIx,
		uint32_t	CRCPoly
	)

Set polynomial for CRC calculation @rmtoll CRCPR CRCPOLY LL_SPI_SetCRCPolynomial.

Parameters

SPIx	SPI Instance
CRCPoly	This parameter must be a number between Min_Data = 0x00 and Max_Data = 0xFFFF

Return values
