In Port Based VLAN Mode
This register indicates the legal egress ports. A “1” on bit 3 means that the packet can be sent to port 3. A “0” on bit
3 means that any packet destined to port 3 will be discarded. This register works with registers 1 to form a 10 bit
mask to all egress ports.
In Tag based VLAN Mode
This is the default VLAN tag. It works with configuration register PVMAP00_1 [7:5] [3:0] to form a default VLAN tag.
If the received packet is untagged, then the packet is classified with the default VLAN tag. If the received packet has
a VLAN ID of 0, then PVID is used to replace the packet’s VLAN ID.

This register is used to change the VLAN priority field of a packet to a
predetermined priority.
1: VLAN priority field is changed to Bit [7:5] at ingress port (Default)
0: Keep VLAN priority field
