(Continued)
DP83816
4.3.6 Auto-Negotiation Link Partner Ability Register
This register contains the advertised abilities of the Link Partner as received during Auto-Negotiation. The content
changes after the successful auto-negotiation if Next-pages are supported.

T4
100BASE-T4 Support:
Default: 0/ RO
1= 100BASE-T4 is supported by the local device
0 = 100BASE-T4 not supported
8
TX_FD
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
7
TX
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

10_FD
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
5
10
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
4:0
Selector
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.

ACK
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.
