GT-48001A Switched Ethernet Controller
Revision 1.6

23
ParEn
Partition Enable.
When more than 32 collisions occur while transmit-
ting, the GT-48001A enters the Partition 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 - Normal mode
1- Partition mode
0x0
24
SpanEn
Spanning Tree Enable.
0 - The BPDU (Bridge Protocol Data Unit) packets are
treated as Multicast packets, and therefore are for-
warded to all ports.
1 - The GT-48001A forwards BPDU packets only to
the CPU.
0x0
25
EnEASE
EASE sampling enable/disable.
0 - EASE sampling disabled.
1 - EASE sampling enabled.
0x0
26
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
27
EnableDevice
Used to enable or disable the GT-48001A.
This bit along with EnDev* (external hardware pin) as
well as EnPort (bit 0 of the Port Control Register)
enables or disables the port/device. See Table 1,
0x0
28
RstQueues
Reset Queues. Used to reset the transmit and receive
queues via software.
0 - The Tx and Rx queues of the GT-48001A are reset
according to RstQueue*.
1 - Reset the Tx and Rx queues immeidately.
0x0
29
CRCGenEn
Used to enable or disable the CRC generation during
transmit of CPU generated packets to the GT-
48001A.
0 - CRC generation is disabled
1 - CRC generation is enabled .
0x0
30
MIBClrMode
MIB Counter Clear-on-Read mode
0 - MIB counters will be cleared after they have been
read.
1 - MIB counters will not cleared after they have been
read.
0x0
31
Reserved
This bit is reserved and must be written to 0.
