8.0 Register Block (Continued)
Advertised abilities of the Link Partner as received during Auto-Negotiation.
7 TX Strap, RW 100BASE-TX Support:
1 = 100BASE-TX is supported by the local device
0 = 100BASE-TX not supported
At reset, this bit is set by AN0/AN1. After reset, this bit may be
written to by software.
6 10_FD Strap, RW 10BASE-T Full Duplex Support:
1 = 10BASE-T Full Duplex is supported by the local device
0 = 10BASE-T Full Duplex not supported
At reset, this bit is set by AN0/AN1. After reset, this bit may be
written to by software.
5 10 Strap, RW 10BASE-T Support:
1 = 10BASE-T is supported by the local device
0 = 10BASE-T not supported
At reset, this bit is set by AN0/AN1. After reset, this bit may be
written to by software.
4:0 Selector <00001>, RW Protocol Selection Bits:
These bits contain the binary encoded protocol selector support-
ed by this node. <00001> indicates that this device supports IEEE
802.3 CSMA/CD.

Bit Bit Name Default Description
15 NP 0, RO Next Page Indication:
0 = Link Partner does not desire Next Page Transfer
1 = Link Partner desires Next Page Transfer
14 ACK 0, RO Acknowledge:
1 = Link Partner acknowledges reception of the ability data word
0 = Not acknowledged
The Device's Auto-Negotiation state machine will automatically
control the use of this bit from the incoming FLP bursts. Software
should not attempt to write to this bit.
13 RF 0, RO Remote Fault:
1 = Remote Fault indicated by Link Partner
0 = No Remote Fault indicated by Link Partner
12:10 Reserved 0, RO Reserved for Future IEEE use: Write as 0, read as 0

1 = 100BASE-T4 is supported by the Link Partner
0 = 100BASE-T4 not supported by the Link Partner
8 TX_FD 0, RO 100BASE-TX Full Duplex Support:
1 = 100BASE-TX Full Duplex is supported by the Link Partner
0 = 100BASE-TX Full Duplex not supported by the Link Partner
7 TX 0, RO 100BASE-TX Support:
1 = 100BASE-TX is supported by the Link Partner
0 = 100BASE-TX not supported by the Link Partner
