Bit Name Description Access Reset
31:0 l3a03
When Bit 0 (L3PEN3) and Bit 2 (L3SAM3) are set in Register 292 (Layer 3 and Layer 4 Control Register 3), this field contains the value to be matched with Bits [31:0] of the IP Source Address field in the IPv6 frames.

When Bit 0 (L3PEN3) and Bit 4 (L3DAM3) are set in Register 292 (Layer 3 and Layer 4 Control Register 3), this field contains the value to be matched with Bits [31:0] of the IP Destination Address field in the IPv6 frames.

When Bit 0 (L3PEN3) is reset and Bit 2 (L3SAM3) is set in Register 292 (Layer 3 and Layer 4 Control Register 3), this field contains the value to be matched with the IP Source Address field in the IPv4 frames.
