Detailed Description

DDL_SPI_DeInit()

ErrorStatus DDL_SPI_DeInit

(

SPI_TypeDef *

SPIx

)

De-initialize the SPI registers to their default reset values.

Parameters

SPIx	SPI Instance

Return values

An	ErrorStatus enumeration value: SUCCESS: SPI registers are de-initialized ERROR: SPI registers are not de-initialized

DDL_SPI_Init()

ErrorStatus DDL_SPI_Init	(	SPI_TypeDef *	SPIx,
		DDL_SPI_InitTypeDef *	SPI_InitStruct )

Initialize the SPI registers according to the specified parameters in SPI_InitStruct.

Note

As some bits in SPI configuration registers can only be written when the SPI is disabled (SPI_CTRL1_SPIEN bit =0), SPI peripheral should be in disabled state prior calling this function. Otherwise, ERROR result will be returned.

Parameters

SPIx	SPI Instance
SPI_InitStruct	pointer to a DDL_SPI_InitTypeDef structure

Return values

An	ErrorStatus enumeration value. (Return always SUCCESS)

Definition at line 174 of file g32r4xx_ddl_spi.c.

DDL_SPI_StructInit()

void DDL_SPI_StructInit

(

DDL_SPI_InitTypeDef *

SPI_InitStruct

)

Set each DDL_SPI_InitTypeDef field to default value.

Parameters

SPI_InitStruct

pointer to a DDL_SPI_InitTypeDef structure whose fields will be set to default values.

Return values

None
