Next page Indication
0 = No next page available
1 = Next page available
The DM9161BI has no next page, so this bit is permanently set to 0
Acknowledge
1 = Link partner ability data reception acknowledged
0 = Not acknowledged
The DM9161BI's auto-negotiation state machine will automatically
control this bit in the outgoing FLP bursts and set it at the
appropriate time during the auto-negotiation process. Software
should not attempt to write to this bit.
Remote Fault
1 = Local device senses a fault condition
0 = No fault detected
Reserved
Write as 0, ignore on read
Flow Control Support
1 = Controller chip supports flow control ability
0 = Controller chip doesn’t support flow control ability
100BASE-T4 Support
1 = 100BASE-T4 is supported by the local device
0 = 100BASE-T4 is not supported
The DM9161BI does not support 100BASE-T4 so this bit is
permanently set to 0
100BASE-TX Full Duplex Support
1 = 100BASE-TX full duplex is supported by the local device
0 = 100BASE-TX full duplex is not supported
100BASE-TX Support
1 = 100BASE-TX half duplex is supported by the local device
0 = 100BASE-TX half duplex is not supported
10BASE-T Full Duplex Support
1 = 10BASE-T full duplex is supported by the local device
0 = 10BASE-T full duplex is not supported
10BASE-T Support
1 = 10BASE-T half duplex is supported by the local device
0 = 10BASE-T half duplex is not supported
These bits contain the binary encoded protocol selector supported
by this node
<00001> indicates that this device supports IEEE 802.3 CSMA/CD
