DATASHEET
FIFO_INT—FIFO Level Interrupts
This register configures the limits where the FIFO Controllers will generate system interrupts.
5.3.7
RX_CFG—Receive Configuration Register
This register controls the LAN9116 receive engine.
Offset:

DESCRIPTION

31-24
TX Data Available Level.
The value in this field sets the level, in number
of 64 Byte blocks, at which the TX FIFO Available interrupt (TFDA) will be
generated. When the TX data FIFO free space is greater than this value a
TX FIFO Available interrupt (TDFA) will be generated.
R/W
48h
23-16
TX Status Level.
The value in this field sets the level, in number of
DWORDs, at which the TX Status FIFO Level interrupt (TSFL) will be
generated. When the TX Status FIFO used space is greater than this value
an TX Status FIFO Level interrupt (TSFL) will be generated.
R/W
00h
15-8
RX Space Available Level.
The value in this field sets the level, in number
of 64 Byte blocks, at which the RX data FIFO Level interrupt (RDFL) will be
generated. When the RX data FIFO free space is less than this value an RX
data FIFO Level interrupt (RDFL) will be generated.
R/W
00h
7-0
RX Status Level.
The value in this field sets the level, in number of
DWORDs, at which the RX Status FIFO Level interrupt (RSFL) will be
generated. When the RX Status FIFO used space is greater than this value
an RX Status FIFO Level interrupt (RSFL) will be generated.

RX End Alignment.
This field specifies the alignment that must be
maintained on the last data transfer of a buffer. The LAN9116 will add
extra DWORDs of data up to the alignment specified in the table below.
The host is responsible for removing these extra DWORDs. This
mechanism can be used to maintain cache line alignment on host
processors.
Please refer to
Table 5.2
for bit definitions
Note:
The desired RX End Alignment must be set before reading a
packet. The RX end alignment can be changed between reading
receive packets, but must not be changed if the packet is
partially read.

RX DMA Count (RX_DMA_CNT).
This 12-bit field indicates the amount
of data, in DWORDS, to be transferred out of the RX data FIFO before
asserting the RXD_INT. After being set, this field is decremented for each
DWORD of data that is read from the RX data FIFO. This field can be
overwritten with a new value before it reaches zero.
