| The configuration structure for AXI DMA engine. More...

## Macros
#define | XAxiDma_GetTxRing(InstancePtr) (&((InstancePtr)->TxBdRing))
| Get Transmit (Tx) Ring ptr. More...
#define | XAxiDma_GetRxRing(InstancePtr) (&((InstancePtr)->RxBdRing[0]))
| Get Receive (Rx) Ring ptr. More...
#define | XAxiDma_GetRxIndexRing(InstancePtr, RingIndex) (&((InstancePtr)->RxBdRing[RingIndex]))
| Get Receive (Rx) Ring ptr of a Index. More...
#define | XAxiDma_HasSg(InstancePtr) ((InstancePtr)->HasSg) ? TRUE : FALSE
| This function checks whether system is configured as Simple or Scatter Gather mode. More...
#define | XAxiDma_IntrEnable(InstancePtr, Mask, Direction)
| This function enables interrupts specified by the Mask in specified direction, Interrupts that are not in the mask are not affected. More...
#define | XAxiDma_IntrGetEnabled(InstancePtr, Direction)
| This function gets the mask for the interrupts that are currently enabled. More...
#define | XAxiDma_IntrDisable(InstancePtr, Mask, Direction)
| This function disables interrupts specified by the Mask. More...
#define | XAxiDma_IntrGetIrq(InstancePtr, Direction)
| This function gets the interrupts that are asserted. More...
#define | XAxiDma_IntrAckIrq(InstancePtr, Mask, Direction)
| This function acknowledges the interrupts that are specified in Mask. More...
