Bit Name Description Access Reset
31:0 l3a20

When Bit 0 (L3PEN0) and Bit 2 (L3SAM0) are set in Register 256 (Layer 3 and Layer 4 Control Register 0), this field contains the value to be matched with Bits [95:64] of the IP Source Address field in the IPv6 frames. When Bit 0 (L3PEN0) and Bit 4 (L3DAM0) are set in Register 256 (Layer 3 and Layer 4 Control Register 0), this field contains value to be matched with Bits [95:64] of the IP Destination Address field in the IPv6 frames. When Bit 0 (L3PEN0) is reset in Register 256 (Layer 3 and Layer 4 Control Register 0), this register is not used.
