Register 3 (0x03): Global Control 1
Bit
Name
R/W
Description
Default
7
Pass all frames
R/W
= 1, switch all packets including bad ones. Used
solely for debugging purposes. Works in conjunction
with sniffer mode only.
0
6
Repeater
mode
R/W
0 = normal mode
1 = repeater mode (half duplex Hub mode)
0
5
IEEE 802.3x
Transmit
direction flow
control enable
R/W
= 1, will enable transmit direction flow control feature.
= 0, will not enable transmit direction flow control
feature.
1
4
IEEE 802.3x
Receive
direction flow
control enable
R/W
= 1, will enable receive direction flow control feature.
= 0, will not enable receive direction flow control
feature.
1
3
Frame Length
field check
R/W
1 = will check frame length field in the IEEE packets.
If the actual length does not match, the packet will be
dropped
(for Length/Type field < 1500).
0
2
Aging enable
R/W
1 = enable age function in the chip
0 = disable age function in the chip
1
Fast age
enable
R/W
1 = turn on fast age (800us)
0
Aggressive
back off enable
R/W
1 = enable more aggressive back off algorithm in half
duplex mode to enhance performance. This is not an
IEEE standard.
SMAC (pin
69) value
during
reset.
Register 4 (0x04): Global Control 2
Bit
Name
R/W
Description
Default
7
Unicast port-
VLAN
mismatch
discard
R/W
This feature is used for port-VLAN (described in reg.
17, reg. 33, …)
= 1, all packets can not cross VLAN
boundary
= 0, unicast packets (excluding
unkown/multicast/broadcast) can cross VLAN
boundary
Note: Port mirroring is not supported if this bit is set to
“0”.

6
Multicast storm
protection
disable
R/W
= 1, “Broadcast Storm Protection” does not include
multicast packets. Only
DA = FFFFFFFFFFFF packets will be
regulated.
= 0, “Broadcast Storm Protection” includes
DA = FFFFFFFFFFFF and DA[40] = 1 packets.

5
Back pressure
Mode
R/W
= 1, carrier sense based backpressure is selected
= 0, collision based backpressure is selected
