Detailed Description

Function Documentation

uint32_t DDL_DMA_DeInit	(	DMA_TypeDef *	DMAx,
		uint32_t	Stream )

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

Parameters

DMAx	DMAx Instance
Stream	This parameter can be one of the following values: DDL_DMA_STREAM_0 DDL_DMA_STREAM_1 DDL_DMA_STREAM_2 DDL_DMA_STREAM_3 DDL_DMA_STREAM_4 DDL_DMA_STREAM_5 DDL_DMA_STREAM_6 DDL_DMA_STREAM_7 DDL_DMA_STREAM_ALL

Return values

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

Definition at line 170 of file g32r4xx_ddl_dma.c.

Initialize the DMA registers according to the specified parameters in DMA_InitStruct.

Note

To convert DMAx_Streamy Instance to DMAx Instance and Streamy, use helper macros :
