None

Definition at line 897 of file g32r4xx_ddl_spi.h.

DDL_SPI_ClearFlag_FRE()

__STATIC_INLINE void DDL_SPI_ClearFlag_FRE

(

SPI_TypeDef *

SPIx

)

Clear frame format error flag.

Note

Clearing this flag is done by reading SPIx_STS register

)

Clear mode fault error flag.

Note

Clearing this flag is done by a read access to the SPIx_STS register followed by a write access to the SPIx_CTRL1 register

Parameters

SPIx	SPI Instance

Return values

None

Definition at line 919 of file g32r4xx_ddl_spi.h.

DDL_SPI_ClearFlag_OVR()

__STATIC_INLINE void DDL_SPI_ClearFlag_OVR

(

SPI_TypeDef *

SPIx

)

Clear overrun error flag.

Note

Clearing this flag is done by a read access to the SPIx_DATA register followed by a read access to the SPIx_SR register

Parameters

SPIx	SPI Instance

Return values

None

Definition at line 944 of file g32r4xx_ddl_spi.h.

__STATIC_INLINE uint32_t DDL_SPI_IsActiveFlag_BSBUSY

(

SPI_TypeDef *

SPIx

)

Get Biss busy flag.

Parameters

SPIx	SPI Instance

Return values

State

of bit (1 or 0).

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
