DDL_SPI_EnableCRC()

__STATIC_INLINE void DDL_SPI_EnableCRC

(

SPI_TypeDef *

SPIx

)

Enable CRC.

Note

This bit should be written only when SPI is disabled (SPE = 0) for correct operation.

Parameters

SPIx	SPI Instance

Return values

__STATIC_INLINE uint32_t DDL_SPI_GetTxCRC

(

SPI_TypeDef *

SPIx

)

Get Tx CRC.

Parameters

SPIx	SPI Instance

DDL_SPI_IsEnabledCRC()

__STATIC_INLINE uint32_t DDL_SPI_IsEnabledCRC

(

SPI_TypeDef *

SPIx

)

Check if CRC is enabled.

Note

This bit should be written only when SPI is disabled (SPE = 0) for correct operation.

Parameters

SPIx	SPI Instance

Return values

State

of bit (1 or 0).

Definition at line 758 of file g32r4xx_ddl_spi.h.

DDL_SPI_SetCRCNext()

__STATIC_INLINE void DDL_SPI_SetCRCNext

(

SPI_TypeDef *

SPIx

)
