PVID registers (register 23)
The PVID registers assign VLAN IDs for each port.
There are 24 PVID registers, one for each port. A
PVID consists of 4 bits, each corresponding to one of
the 4 VLANs. A port can belong to more than one
VLAN at the same time. Table-7.23 describes the bits
of one of the registers.

VPID registers (register 24)
The VPID registers specify the dumping port for each
VLAN. There are 4 VPID 5-bit registers, one for each
VLAN. A valid VPID are “0” through “23” (other values
are reserved and should not used). Table-7.24 de-
scribes the bits one of the registers.
