DESCRIPTION
RX Data FIFO Fast Forward (RX_FFWD): Writing a ‘1’ to this bit causes
the RX data FIFO to fast-forward to the start of the next frame. This bit will
remain high until the RX data FIFO fast-forward operation has completed.
No reads should be issued to the RX data FIFO while this bit is high.
Note:
Reserved
DESCRIPTION
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).
RX_DP_CTRL—Receive Datapath Control Register
This register is used to discard unwanted receive frames.
RX_FIFO_INF—Receive FIFO Information Register
This register contains the used space in the receive FIFOs of the LAN9118 Ethernet Controller.
