Ethernet Controller with General Processor Interface
X, RW Reserved
Write as 0, ignore on read
0, RW Flow Control Support
1 = Controller chip supports flow control ability
0 = Controller chip doesn’t support flow control ability
0, RO/P 100BASE-T4 Support
1 = 100BASE-T4 is supported by the local device
0 = 100BASE-T4 is not supported
The DM9008C does not support 100BASE-T4 so this bit is
permanently set to 0
1, RW 100BASE-TX Full Duplex Support
1 = 100BASE-TX full duplex is supported by the local device
0 = 100BASE-TX full duplex is not supported
(The DM9008C only support 100M Fiber mode).
1, RW Reserved
1, RW 10BASE-T Full Duplex Support
1 = 10BASE-T full duplex is supported by the local device
0 = 10BASE-T full duplex is not supported
1, RW 10BASE-T Support
1 = 10BASE-T half duplex is supported by the local device
0 = 10BASE-T half duplex is not supported
<00001>, RW 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
8.6 Auto-negotiation Link Partner Ability Register (ANLPAR) – 05

Description
Next Page Indication
0 = Link partner, no next page available
1 = Link partner, next page available
Acknowledge
1 = Link partner ability data reception acknowledged
0 = Not acknowledged
The DM9008C's auto-negotiation state machine will automatically
control this bit from the incoming FLP bursts. Software should not
attempt to write to this bit
Remote Fault
1 = Remote fault indicated by link partner
0 = No remote fault indicated by link partner
Reserved
Read as 0, ignore on write
Flow Control Support
1 = Controller chip supports flow control ability by link partner
0 = Controller chip doesn’t support flow control ability by link
partner
100BASE-T4 Support
1 = 100BASE-T4 is supported by the link partner
0 = 100BASE-T4 is not supported by the link partner
