Registers 19 and 20 (and those corresponding to other ports) serve two purposes:
a.
Associated with the ingress untagged packets, and used for egress tagging.
b.
Default VID for the ingress untagged or null-VID-tagged packets, and used for address lookup.

=0, Port 3 MII PHY mode
Note:
Bit 7 is reserved in the port 1 and port 2 of the port register control
5. But request to set the register 21 port 1 control 5 bit [7] = ‘1’ for
better EMI, because this bit 7 of the register 21 is for port 1 MII of
the MML part. In the MLL/FLL/RLL parts, setting this bit will disable
the unused internal 25MHz clock for the unused port 1 MII PHY
mode circuits.
