Ingress VLAN
filtering
R/W
= 1, the switch will discard packets whose VID
port membership in VLAN table bits [18:16] does
not include the ingress port.
= 0, no ingress VLAN filtering.
0
5
Discard non
PVID packets
R/W
= 1, the switch will discard packets whose VID
does not match ingress port default VID.
= 0, no packets will be discarded
0
4
Force flow
control
R/W
= 1, will always enable flow control on the port,
regardless of AN result.
= 0, the flow control is enabled based on AN
result.
Pin value during
reset:
For port 1,
P1FFC pin
For port 2,
P2FFC pin
For port 3, this
bit has no
meaning. Flow
control is
controlled by
Reg. 6, bit 5.
3
Back pressure
enable
R/W
= 1, enable port’s half duplex back pressure
= 0, disable port’s half duplex back pressure.
Pin value during
reset:
BPEN pin
2
Transmit
enable
R/W
= 1, enable packet transmission on the port
= 0, disable packet transmission on the port
1
Receive
enable
R/W
= 1, enable packet reception on the port
= 0, disable packet reception on the port
1
0
Learning
disable
R/W
= 1, disable switch address learning capability
= 0, enable switch address learning
0
Note: Bits [2:0] are used for spanning tree support (see page 33).
