## Functions
u32 | XLlFifo_iRxOccupancy (XLlFifo *InstancePtr)
| XLlFifo_iRxOccupancy returns the number of 32-bit words available (occupancy) to be read from the receive channel of the FIFO, specified by InstancePtr. More...
u32 | XLlFifo_iRxGetLen (XLlFifo *InstancePtr)
| XLlFifo_iRxGetLen notifies the hardware that the program is ready to receive the next frame from the receive channel of the FIFO specified by InstancePtr. More...
int | XLlFifo_iRead_Aligned (XLlFifo *InstancePtr, void *BufPtr, unsigned WordCount)
| XLlFifo_iRead_Aligned reads, WordCount, words from the FIFO referenced by InstancePtr to the block of memory, referenced by BufPtr. More...
u32 | XLlFifo_iTxVacancy (XLlFifo *InstancePtr)
| XLlFifo_iTxVacancy returns the number of unused 32 bit words available (vacancy) in the send channel of the FIFO, specified by InstancePtr. More...
void | XLlFifo_iTxSetLen (XLlFifo *InstancePtr, u32 Bytes)
| XLlFifo_iTxSetLen begins a hardware transfer of data out of the transmit channel of the FIFO, specified by InstancePtr. More...
int | XLlFifo_iWrite_Aligned (XLlFifo *InstancePtr, void *BufPtr, unsigned WordCount)
| XLlFifo_iWrite_Aligned writes, WordCount, words to the FIFO referenced by InstancePtr from the block of memory, referenced by BufPtr. More...
int | XLlFifo_CfgInitialize (XLlFifo *InstancePtr, XLlFifo_Config *Config, UINTPTR EffectiveAddress)
| XLlFifo_CfgInitialize initializes an XPS_ll_Fifo device along with the InstancePtr that references it. More...
u32 | XLlFifo_RxGetWord (XLlFifo *InstancePtr)
| XLlFifo_RxGetWord reads one 32 bit word from the FIFO specified by InstancePtr. More...
void | XLlFifo_TxPutWord (XLlFifo *InstancePtr, u32 Word)
| XLlFifo_TxPutWord writes the 32 bit word, Word to the FIFO specified by InstancePtr. More...
void | XLlFifo_Initialize (XLlFifo *InstancePtr, UINTPTR BaseAddress)
| XLlFifo_Initialize initializes an XPS_ll_Fifo device along with the InstancePtr that references it. More...
