Detailed Description
Function Documentation
◆ LL_SPI_ClearFlag_CRCERR()
| __STATIC_INLINE void LL_SPI_ClearFlag_CRCERR | ( | SPI_TypeDef * | SPIx | ) |
Clear CRC error flag @rmtoll SR CRCERR LL_SPI_ClearFlag_CRCERR.
- Parameters
-
SPIx SPI Instance
- Return values
-
None
Definition at line 815 of file stm32f4xx_ll_spi.h.
◆ LL_SPI_ClearFlag_FRE()
| __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 @rmtoll SR FRE LL_SPI_ClearFlag_FRE
- Parameters
-
SPIx SPI Instance
- Return values
-
None
Definition at line 860 of file stm32f4xx_ll_spi.h.
◆ LL_SPI_ClearFlag_MODF()
| __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 @rmtoll SR MODF LL_SPI_ClearFlag_MODF
- Parameters
-
SPIx SPI Instance
- Return values
-
None
Definition at line 828 of file stm32f4xx_ll_spi.h.
◆ LL_SPI_ClearFlag_OVR()
| __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 @rmtoll SR OVR LL_SPI_ClearFlag_OVR
- Parameters
-
SPIx SPI Instance
- Return values
-
None
Definition at line 844 of file stm32f4xx_ll_spi.h.
◆ LL_SPI_IsActiveFlag_BSY()
| __STATIC_INLINE uint32_t LL_SPI_IsActiveFlag_BSY | ( | const 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. @rmtoll SR BSY LL_SPI_IsActiveFlag_BSY
- Parameters
-
SPIx SPI Instance
- Return values
-
State of bit (1 or 0).
Definition at line 793 of file stm32f4xx_ll_spi.h.
