Good Link
0 Link pulses are being received by the port
1 Link pulses are not being received by the port logic
Note Writing a 1 to this bit will cause the 10BASE-T transceiver not to transmit or monitor the reception of link
pulses If the internal 10BASE-T transceivers are not selected or if port 1 (AUI port) is read then this bit is undefined
Collision
0 A collision is happening or has occurred during the current packet
1 No collisions have occurred as yet during this packet
Receive
0 This port is now or has been the receive source of packet or collision information for the current
packet
1 This port has not been the receive source during the current packet
Partition
0 This port is partitioned
1 This port is not partitioned
Writing a logic one to this bit forces segment reconnection and partition state machine reset Writing
a zero to this bit has no effect
Squelch Level
0 Port operates with normal IEEE receive squelch level
1 Port operates with reduced receive squelch levels
Note This bit has no effect when the external transceiver is selected
Polarity
0 Polarity is not inverted
1 Polarity is inverted
‘‘Reserved’’
‘‘Value set to logic zero’’
Disable Port
0 Port operates as defined by repeater operations
1 All port activity is prevented
