Description
Next page indication:
0 = No next page available
The PHY does not support the next page function.
Acknowledgement:
1 = Link partner ability data reception acknowledged
0 = Not acknowledged
Remote fault:
1 = Fault condition detected and advertised
0 = No fault detected
Reserved:
Write as 0, read as “don’t care”.
Pause:
1 = Pause operation enabled for full-duplex links
0 = Pause operation not enabled
100BASE-T4 support:
0 = 100BASE-T4 not supported
100BASE-TX full-duplex support:
1 = 100BASE-TX full-duplex supported by this device
0 = 100BASE-TX full-duplex not supported by this device
100BASE-TX half-duplex support:
1 = 100BASE-TX half-duplex supported by this device
0 = 100BASE-TX half-duplex not supported by this device
10BASE-T full-duplex support:
1 = 10BASE-T full-duplex supported by this PHY
0 = 10BASE-T full-duplex not supported by this PHY
10BASE-T half-duplex support:
1 = 10BASE-T half-duplex supported by this PHY
0 = 10BASE-T half-duplex not supported by this PHY
Protocol selection bits:
These bits contain the binary encoded protocol selector supported
by this PHY. [0 0001] indicates that this PHY supports IEEE
802.3u CSMA/CD.
