This graph shows which files directly or indirectly include this file:

Data Structures
struct	DMAMSPM0_HWAttrs
	DMAMSPM0 Hardware attributes. More...

struct	DMAMSPM0_Transfer
	DMAMSPM0 channel based Transfer configuration. More...

struct	DMAMSPM0_Object
	DMAMSPM0 object. More...

struct	DMAMSPM0_Cfg
	DMAMSPM0 Global configuration. More...

Macros
#define	NUM_DMA_CHANNELS (DMA_SYS_N_DMA_CHANNEL)
	Number of DMA channels supported by Device. The same can be used to define the number of interrupts. More...

Typedefs
typedef void(*	DMAMSPM0_IsrFxn) (uintptr_t arg)
	DMA error function pointers.

typedef DMAMSPM0_Cfg *	DMAMSPM0_Handle
	A handle that is returned from a DMAMSPM0_open() call.

Functions
void	DMAMSPM0_close (DMA_Regs *handle, uint8_t channelNum)
	Function to close the DMA channel. More...

bool	DMAMSPM0_init (void)
	Function to initialize the MSPM0 DMA driver. More...

DMAMSPM0_Handle	DMAMSPM0_open (uint_least8_t index, uint8_t channelNum)
	Function to initialize the MSPM0 DMA peripheral and corresponding interrupt. More...

bool	DMAMSPM0_setupTransfer (DMAMSPM0_Transfer transfer, DL_DMA_Config DMACfg)
	Function to set up a DMA channel for data transfer. More...

DMAMSPM0_Handle	DMA_Init (DMAMSPM0_Transfer dmaParams, DL_DMA_Config DMACfg, uint8_t noOfChs)
	One Function that initialize DMA by calling all needed functions in sequence. User may call this function to initialize DMA without calling other needed functions separately. More...

void	DMAMSPM0_disableChannel (DMAMSPM0_Handle handle, uint8_t dmaChannel)
	This function will disable the channel and related flags. More...

uint16_t	DMAMSPM0_getCurrTransferSize (uint8_t dmaChannel)
	This function will return the DMA transfer size in bytes for given channel. More...

void	DMA_Params_init (DMAMSPM0_Transfer *params)
	This function will initialize the default params. More...

void	DMAMSPM0_copyDMAParams (DMAMSPM0_Transfer dmaParams, DL_DMA_Config dmaConfig)
	This function will extract parameters from DMA Config struct to DMA Transfer struct. More...

Variables
const DMAMSPM0_Cfg	DMAMSPM0_Config []
	Instance of a DMA Config structure.

const uint_least8_t	DMA_Count
	Number of DMA channels.
