Reserved
RX Status FIFO Used Space (RXSUSED). Indicates the amount of space
in DWORDs, used in the RX Status FIFO.
RX Data FIFO Used Space (RXDUSED).). Reads the amount of space in
bytes, used in the RX data FIFO. For each receive frame, this field is
incremented by the length of the receive data rounded up to the nearest
DWORD (if the payload does not end on a DWORD boundary).
Reserved
TX Status FIFO Used Space (TXSUSED). Indicates the amount of space
in DWORDS used in the TX Status FIFO.
TX Data FIFO Free Space (TDFREE). Reads the amount of space in bytes,
available in the TX data FIFO. The application should never write more data
than is available, as indicated by this value.
RX_FIFO_INF—Receive FIFO Information Register
This register contains the used space in the receive FIFOs of the LAN9217 Ethernet Controller.
TX_FIFO_INF—Transmit FIFO Information Register
This register contains the free space in the transmit data FIFO and the used space in the transmit
status FIFO in the LAN9217.
