Function Documentation

__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 771 of file stm32f1xx_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 816 of file stm32f1xx_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

Reference Manual to LL API cross reference:

SR MODF LL_SPI_ClearFlag_MODF

Parameters:

SPIx	SPI Instance

Return values:

None

Definition at line 784 of file stm32f1xx_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

Definition at line 800 of file stm32f1xx_ll_spi.h.

__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.

Reference Manual to LL API cross reference:

SR BSY LL_SPI_IsActiveFlag_BSY

Parameters:

SPIx	SPI Instance

Return values:

State

of bit (1 or 0).

Definition at line 759 of file stm32f1xx_ll_spi.h.
