Layer3_Addr1_Reg2

For IPv4 frames, the Layer 3 Address 1 Register 2 contains the 32-bit IP Destination Address field. For IPv6 frames, it contains Bits [63:32] of the 128-bit IP Source Address or Destination Address field.

Layer3_Addr1_Reg2 Fields

Bit	Name	Description	Access	Reset
31:0	`l3a12`	Layer 3 Address 1 Field When Bit 0 (L3PEN2) and Bit 2 (L3SAM2) are set in Register 280 (Layer 3 and Layer 4 Control Register 2), this field contains the value to be matched with Bits [63:32] of the IP Source Address field in the IPv6 frames. When Bit 0 (L3PEN2) and Bit 4 (L3DAM2) are set in Register 280 (Layer 3 and Layer 4 Control Register 2), this field contains the value to be matched with Bits [63:32] of the IP Destination Address field in the IPv6 frames. When Bit 0 (L3PEN2) is reset and Bit 4 (L3DAM2) is set in Register 280 (Layer 3 and Layer 4 Control Register 2), this field contains the value to be matched with the IP Destination Address field in the IPv4 frames.	`RW`	`0x0`
