Next page Indication
The DM8603 has no next page, so this bit is permanently set to 0.
Acknowledge
The DM8603'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
Reserved
Write as 00b, ignore when read
Flow Control Support
100BASE-T4 Support
The DM8603 does not support 100BASE-T4 so this bit is
permanently set to 0

100BASE-TX Support
10BASE-T Full Duplex Support
10BASE-T Support
Protocol Selection Bits
These bits contain the binary encoded protocol selector supported by
this node
<00001> indicates that this device supports IEEE 802.3 CSMA/CD
0 = No next page available
1 = Next page available
1 = Link partner ability data reception acknowledged
0 = Not acknowledged
1 = Local device senses a fault condition
0 = No fault detected
1 = Controller chip supports flow control ability
0 = Controller chip doesn’t support flow control ability
1 = 100BASE-T4 is supported by the local device
0 = 100BASE-T4 is not supported
1 = 100BASE-TX full duplex is supported by the local device
0 = 100BASE-TX full duplex is not supported
1 = 100BASE-TX half duplex is supported by the local device
