Datasheet
23.3.44 Added Qtag Value Set Register (Port 0 to 1) (TSU_ADQT0)
TSU_ADQT0 sets the Qtag data to be added in the conversion of normal Ethernet frames (no
Qtag) to IEEE802.1Q frames (with Qtag) in port 0 to 1 relay operations (if bits QTAG0[2:0] in
TSU_QTAG0 are set to H'3 or H'7 when using the Qtag adding function). This register must not
be written to once after relay operations have been enabled (after the FWEN0 bit in TSU_FWEN0
or the FWEN1 bit in TSU_FWEN1 is set to 1).

(QTAG0[31:16]) as H'8100 (indicates the Qtag
extension frame format is used). The value read is
H'8100.
These bits set the processing priority of frames with
Qtag. For details on the settings, refer to the
specifications on Qtag control specified in IEEE802.1Q.
Reserved
This bit is always read as 0. The write value should
always be 0.
These bits should be set when frames with Qtag are to
be used in systems supporting V-LAN. For details on
settings, refer to the specifications on Qtag control
specified in IEEE802.1Q.
