Layer4_Address2

Because the Layer 3 and Layer 4 Address Registers are double-synchronized to the Rx clock domains, then the synchronization is triggered only when Bits[31:24] (in little-endian mode) or Bits[7:0] (in big-endian mode) of the Layer 3 and Layer 4 Address Registers are written. For proper synchronization updates, you should perform the consecutive writes to the same Layer 3 and Layer 4 Address Registers after at least four clock cycles delay of the destination clock.

Layer4_Address2 Fields

Bit Name Description Access Reset
31:16 l4dp2

When Bit 16 (L4PEN2) is reset and Bit 20 (L4DPM2) is set in Register 280 (Layer 3 and Layer 4 Control Register 2), this field contains the value to be matched with the TCP Destination Port Number field in the IPv4 or IPv6 frames. When Bit 16 (L4PEN2) and Bit 20 (L4DPM2) are set in Register 280 (Layer 3 and Layer 4 Control Register 2), this field contains the value to be matched with the UDP Destination Port Number field in the IPv4 or IPv6 frames.

RW 0x0
15:0 l4sp2

When Bit 16 (L4PEN2) is reset and Bit 20 (L4DPM2) is set in Register 280 (Layer 3 and Layer 4 Control Register 2), this field contains the value to be matched with the TCP Source Port Number field in the IPv4 or IPv6 frames. When Bit 16 (L4PEN2) and Bit 20 (L4DPM2) are set in Register 280 (Layer 3 and Layer 4 Control Register 2), this field contains the value to be matched with the UDP Source Port Number field in the IPv4 or IPv6 frames.
