5.4.10 VLAN2—VLAN2 Tag Register
Offset:
Default Value:
A
00000000h
Attribute:
Size:
R/W
32 bits
This register contains the VLAN tag field to identify VLAN2 frames. For VLAN frames the legal frame
length is increased from 1518 bytes to 1522 bytes.
BITS
31-16
15-0
DESCRIPTION
Reserved
VLAN2 Tag Identifier (VTI2). This contains the VLAN Tag field to identify the VLAN2 frames. This
field is compared with the 13th and 14th bytes of the incoming frames for VLAN2 frame detection.If
used, this register must be set to 0x8100.
5.4.11 WUFF—Wake-up Frame Filter
Offset:
Default Value:
B
00000000h
Attribute:
Size:
This register is used to configure the wake up frame filter.
WO
32 bits
BITS

DESCRIPTION
Wake-Up Frame Filter (WFF). Wake-Up Frame Filter (WFF). The Wake-up frame filter is configured
through this register using an indexing mechanism. After power-on reset, hardware reset, or soft reset,
the MAC loads the first value written to this location to the first DWORD in the Wake-up frame filter
(filter 0 byte mask). The second value written to this location is loaded to the second DWORD in the
wake-up frame filter (filter 1 byte mask) and so on. Once all eight DWORDs have been written, the
internal pointer will once again point to the first entry and the filter entries can be modified in the same
manner.
Note: This is a write-only register.
