void XCsuDma_Transfer (XCsuDma *InstancePtr, XCsuDma_Channel Channel, UINTPTR Addr, u32 Size, u8 EnDataLast)
 This function sets the starting address and amount(size) of the data to be transfered 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 transfered 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 pause the Channel data tranfer to/from memory or to/from stream based on pause type. More...
 
s32 XCsuDma_IsPaused (XCsuDma *InstancePtr, XCsuDma_Channel Channel, XCsuDma_PauseType Type)
 This functions checks whether Channel's memory or stream is paused or not 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 or no effect if it is not in paused state, based on the type of pause. More...
 
u32 XCsuDma_GetCheckSum (XCsuDma *InstancePtr)
