Functions
s32	XCsuDma_CfgInitialize (XCsuDma *InstancePtr, XCsuDma_Config *CfgPtr, UINTPTR EffectiveAddr)
	This function initializes CSU_DMA core. More...
void	XCsuDma_Transfer (XCsuDma *InstancePtr, XCsuDma_Channel Channel, u64 Addr, u32 Size, u8 EnDataLast)
	This function sets the starting address and size of the data to be transferred from/to the memory through the AXI interface. More...
void	XCsuDma_64BitTransfer (XCsuDma *InstancePtr, XCsuDma_Channel Channel, u32 AddrLow, u32 AddrHigh, u32 Size, u8 EnDataLast)
	This function sets the starting address and size of the data to be transferred from/to the memory through the AXI interface. More...
u64	XCsuDma_GetAddr (XCsuDma *InstancePtr, XCsuDma_Channel Channel)
	This function returns the current address location of the memory, from where it has to read the data(SRC) or the location where it has to write the data (DST) based on the channel selection. More...
u32	XCsuDma_GetSize (XCsuDma *InstancePtr, XCsuDma_Channel Channel)
	This function returns the size of the data yet to be transferred from memory to CSU_DMA or CSU_DMA to memory based on the channel selection. More...
void	XCsuDma_Pause (XCsuDma *InstancePtr, XCsuDma_Channel Channel, XCsuDma_PauseType Type)
	This function pauses the Channel data transfer to/from memory or to/from stream based on pause type. More...
s32	XCsuDma_IsPaused (XCsuDma *InstancePtr, XCsuDma_Channel Channel, XCsuDma_PauseType Type)
	This function checks whether Channel memory/stream is paused based on the given pause type. More...
void	XCsuDma_Resume (XCsuDma *InstancePtr, XCsuDma_Channel Channel, XCsuDma_PauseType Type)
	This function resumes the channel if it is in paused state and continues where it has left. More...
u32	XCsuDma_GetCheckSum (XCsuDma *InstancePtr)
	This function returns the sum of all the data read from AXI memory. More...
void	XCsuDma_ClearCheckSum (XCsuDma *InstancePtr)
	This function clears the check sum of the data read from AXI memory. More...
u32	XCsuDma_WaitForDoneTimeout (XCsuDma *InstancePtr, XCsuDma_Channel Channel)
	This function polls for completion of data transfer periodically until the DMA done bit set or until the timeout occurs. More...
void	XCsuDma_SetConfig (XCsuDma *InstancePtr, XCsuDma_Channel Channel, XCsuDma_Configure *ConfigurValues)
	This function configures all the values of CSU_DMA Channels with the values of updated XCsuDma_Configure structure. More...
void	XCsuDma_GetConfig (XCsuDma *InstancePtr, XCsuDma_Channel Channel, XCsuDma_Configure *ConfigurValues)
