## Functions
s32 | XCsuDma_CfgInitialize (XCsuDma *InstancePtr, XCsuDma_Config *CfgPtr, u32 EffectiveAddr)
| This function initializes an CSU_DMA core. More...
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...
void | XCsuDma_64BitTransfer (XCsuDma *InstancePtr, XCsuDma_Channel Channel, u32 AddrLow, u32 AddrHigh, 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)
| 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 will poll for completion of data transfer periodically until DMA done bit set or till the timeout occurs. More...
void | XCsuDma_SetConfig (XCsuDma *InstancePtr, XCsuDma_Channel Channel, XCsuDma_Configure *ConfigurValues)
| This function cofigures all the values of CSU_DMA's Channels with the values of updated XCsuDma_Configure structure. More...
void | XCsuDma_GetConfig (XCsuDma *InstancePtr, XCsuDma_Channel Channel, XCsuDma_Configure *ConfigurValues)
| This function updates XCsuDma_Configure structure members with the cofigured values of CSU_DMA's Channel. More...
