Important: The value of a reserved bit must be maintained in software. When you modify registers containing reserved bit fields, you must use a read-modify-write operation to preserve state and prevent indeterminate system behavior.

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 [63:32] 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 [63:32] of the IP Destination Address field in the IPv6 frames. When Bit 0 (L3PEN3) is reset and Bit 4 (L3DAM3) is set in Register 292 (Layer 3 and Layer 4 Control Register 3), this field contains the value to be matched with the IP Destination Address field in the IPv4 frames. |
