ParEn
Partition Enable.
When more than 32 collisions occur on a 10Mbps
port, or more than 60 collisions occur on a 100Mbps
port while transmitting, the GT-482xx enters the Par-
tition mode. It waits for the first good packet from the
wire, and then goes back to Normal mode. Under
Partition mode it continues transmitting, but not
receiving.
0 - Partition mode Disabled
1 - Partition mode Enabled
0x0
16
SpanEn
Spanning Tree Enable.
0 - The BPDU (Bridge Protocol Data Unit) packets
are treated as Multicast packets, and therefore are
forwarded to all ports.
1 - the GT-482xx forwards BPDU packets only to the
CPU.
0x0
17
EnEASE
EASE sampling enable/disable.
0 - EASE sampling disabled.
1 - EASE sampling enabled.
Must be set if EASE is initialized and any of the ports
are enabled.
NOTE: Bit 8 must be set to ‘1’ (CPU Enabled) prior to
setting this bit to ‘1’..
0x0
18
EnErrSource
Errored Source Address enable/disable.
0 - Error Source disabled.
1 - Error Source enabled.
0x0
19
MIBCtrMode
0 - MIB counters reflect forwarded packets only.
1 - MIB counters reflect local and forwarded packets.
NOTE: A local packet is a packet which is destined to
a station on the same port and is not switched.
0x0
20
EnableDevice
Used in conjunction with EnDev* pin to enable or dis-
able the GT-482xx. Refer to EnDev* description for
more information.
0x0
21
MIBClrMode
MIB Counter Clear-on-Read mode
0 - MIB counters will be cleared after they have been
read.
1 - MIB counters will not be cleared after they have
been read.
0x0
22
IgmpEn
IGMP Enable
0 - Treats IGMP packets as Multicast and send to all
ports
1- Send IGMP only to the CPU
0x0
