100BASE-T4 Support: Default: 0/ RO
1= 100BASE-T4 is supported by the local device
0 = 100BASE-T4 not supported
100BASE-TX Full Duplex Support: Default: dependent on setting of the ANEG_SEL in the CFG register
1 = 100BASE-TX Full Duplex is supported by the local device
0 = 100BASE-TX Full Duplex not supported
100BASE-TX Support: Default: dependent on the setting of the ANEG_SEL bits in the CFG register
1 = 100BASE-TX is supported by the local device
0 = 100BASE-TX not supported
10BASE-T Full Duplex Support: Default: dependent on setting of the ANEG_SEL in the CFG register
1 = 10BASE-T Full Duplex is supported by the local device
0 = 10BASE-T Full Duplex not supported
10BASE-T Support: Default: dependent on the setting of the ANEG_SEL bits in the CFG register
1 = 10BASE-T is supported by the local device
0 = 10BASE-T not supported
Protocol Selection Bits: Default: <00001>
These bits contain the binary encoded protocol selector supported by this port. <00001> indicates that
this device supports IEEE 802.3u.
Next Page Indication:
0 = Link Partner does not desire Next Page Transfer
1 = Link Partner desires Next Page Transfer
Acknowledge:
1 = Link Partner acknowledges reception of the ability data word
0 = Not acknowledged
The Device's Auto-Negotiation state machine will automatically control this bit based on the incoming FLP
bursts.
Remote Fault:
1 = Remote Fault indicated by Link Partner
0 = No Remote Fault indicated by Link Partner
Reserved for Future IEEE use: Write as 0, read as 0
100BASE-T4 Support:
1 = 100BASE-T4 is supported by the Link Partner
