DM9102A
Single Chip Fast Ethernet NIC controller
1=Local Device senses a fault condition
0=No fault detected
4.12-4.11
Reserved
00, RW
Reserved:
Write as 0, ignore on read
4.10
FCS
0, RW
Flow Control Support:
1=Controller chip supports flow control ability
0=Controller chip doesn’t support flow control ability
4.9
T4
0, RO/P
100BASE-T4 Support:
1=100BASE-T4 supported by the local device
0=100BASE-T4 not supported
The DM9102A does not support 100BASE-T4 so this bit is permanently
4.8
TX_FDX
1, RW
100BASE-TX Full Duplex Support:
1=100BASE-TX Full Duplex supported by the local device
4.7
TX_HDX
1, RW

10BASE-T Support:
1=10BASE-T supported by the local device
0=10BASE-T not supported
4.4-4.0
Selector
<00001>,
RW
These bits contain the binary encoded protocol selector supported by this
node. <00001> indicates that this device supports IEEE 802.3 CSMA/CD.

Default
5.15
NP
0, RO
Next Page Indication:
0= Link partner, no next page available
1= Link partner, next page available
5.14
ACK
0, RO
Acknowledge:
1=Link partner ability data reception acknowledged
0=Not acknowledged
The DM9102A's Auto-negotiation state machine will automatically control this
bit from the incoming FLP bursts. Software should not attempt to write to this
bit.
