RXDP(N)CFG1 – Receive Data Path Buffer #N Configuration 1
BIT
NAME
TYPE
RESET
1
ROM
RW
FUNCTION
0
Configuration ROM When ROM is set to 1, the corresponding buffer
only receives asynchronous packets that have destination addresses
within the ROM space, specified in IEEE-1394-1995 3.3. This bit is
ignored if RcvAllAddr is set or when this buffer is configured for
isochronous receive.
0
INITUNIT
RW
0
Initial units space When initial unit is set to 1, the corresponding buffer
only receives asynchronous packets that have destination addresses
within the initial units space, specified in IEEE-1394-1995 3.3. This bit
is ignored if RcvAllAddr is set or when this buffer is configured for
isochronous receive.

RXDP(N)CFG2 – Receive Data Path Buffer #N Configuration 2
BIT
NAME
TYPE
RESET
FUNCTION
31:16
SRCIDFILTER
MASK
RW
0
Source ID filter mask – This field contains a bit pattern which masks
certain bit positions of the 16-bit source ID of asynchronous packets.
Default value: 0.
Example:
Mask: 16’b 0000_0000_0000_0001
Filter: 16’b 0000_0000_0000_0000
In this case only even source IDs are received.
Mask: 16’b 0000_0000_0000_0000
Filter: 16’b 0000_0000_0000_0000
In this case every packet is received.
Mask: 16’b 1111_1111_1111_1111
Filter: 16’b 0000_0000_0000_0100
In this case only packets with source ID 16’h4 are received.

Source ID filter – This field contains the expected values at the bit
positions specified in the mask field.

HDR0LOMSK
RW
0
Header 0 lower 16 bit mask This field contains a bit pattern which
masks certain bit positions of the lower 16 bits of the first header quadlet
of a packet.

HDR0LOFLTR
RW
0
Header 0 lower 16 bit filter This field contains the expected values at
the bit positions, specified in the mask field.

DATALENGTH_MASK
RW
0
Data length mask This field contains a bit pattern which
masks certain bit positions of the data length field of the
incoming packet.
15:0
DATALENGTH_FILTER
RW
0
Data length filter This field contains the expected values at
the bit positions specified in the mask field.
