Port4’s embedded and isolated PHY will be connected to the WAN port. CPU will act as the bridge to translate the
packet’s frame for LAN/WAN and use different MII to handle the packets either from LAN to WAN or from WAN to
LAN. The isolated PHY is helpful to reduce the BOM cost.

Step 2: CPU must re-define the Special TAG for the Receive to determine the destination group.
Step 3: If MAC_CLONE function is enabled, CPU must set LRN parameter to disable learning mechanism for
specific packet.
9, it shows an easy way to connect the CPU with dual MII for the routing application. In this application,
