__STATIC_INLINE void LL_SPI_ClearFlag_CRCERR ( SPI_TypeDef * SPIx )

Clear CRC error flag.

Reference Manual to LL API cross reference:: SR CRCERR LL_SPI_ClearFlag_CRCERR

Parameters:

SPIx	SPI Instance

Return values:

None

Definition at line 1036 of file stm32l4xx_ll_spi.h.

__STATIC_INLINE void LL_SPI_ClearFlag_FRE ( SPI_TypeDef * SPIx )

Clear frame format error flag.

Note:: Clearing this flag is done by reading SPIx_SR register

Reference Manual to LL API cross reference:: SR FRE LL_SPI_ClearFlag_FRE

Parameters:

SPIx	SPI Instance

Return values:

None

Definition at line 1082 of file stm32l4xx_ll_spi.h.

__STATIC_INLINE void LL_SPI_ClearFlag_MODF ( SPI_TypeDef * SPIx )

Clear mode fault error flag.

Note:: Clearing this flag is done by a read access to the SPIx_SR register followed by a write access to the SPIx_CR1 register

Parameters:

SPIx	SPI Instance

Return values:

None

Definition at line 1049 of file stm32l4xx_ll_spi.h.

__STATIC_INLINE void LL_SPI_ClearFlag_OVR ( SPI_TypeDef * SPIx )

Clear overrun error flag.

Note:: Clearing this flag is done by a read access to the SPIx_DR register followed by a read access to the SPIx_SR register

Reference Manual to LL API cross reference:: SR OVR LL_SPI_ClearFlag_OVR

Parameters:

SPIx	SPI Instance

Return values:

None

__STATIC_INLINE uint32_t LL_SPI_IsActiveFlag_BSY ( SPI_TypeDef * SPIx )

Get busy flag.

Note:: The BSY flag is cleared under any one of the following conditions: -When the SPI is correctly disabled -When a fault is detected in Master mode (MODF bit set to 1) -In Master mode, when it finishes a data transmission and no new data is ready to be sent -In Slave mode, when the BSY flag is set to '0' for at least one SPI clock cycle between each data transfer.

Parameters:

SPIx	SPI Instance

Return values:

State of bit (1 or 0).
