RX_FIFO_INF—Receive FIFO Information Register  
Offset:  
7Ch  
Size:  
32 bits  
This register contains the used space in the receive FIFOs of the LAN9215I Ethernet Controller.  
BITS  
31-24  
23-16  
DESCRIPTION  
TYPE  
RO  
DEFAULT  
Reserved  
-
RX Status FIFO Used Space (RXSUSED). Indicates the amount of space  
in DWORDs, used in the RX Status FIFO.  
RO  
00h  
15-0  
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).
