8.5 Auto-negotiation Advertisement Register (ANAR) - 04
This register contains the advertised abilities of this DM9000A device as they will be transmitted to its
link partner during Auto-negotiation.
Bit
Bit Name
Default
4.15
NP
0,RO/P
Next page Indication
0 = No next page available
1 = Next page available
The DM9000A has no next page, so this bit is permanently
set to 0
4.14
ACK
0,RO
Acknowledge
1 = Link partner ability data reception acknowledged
0 = Not acknowledged
The DM9000A'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.
4.13
RF
0, RW
Remote Fault
1 = Local device senses a fault condition
0 = No fault detected
4.12-4.1
1
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 is supported by the local device
0 = 100BASE-T4 is not supported
The DM9000A does not support 100BASE-T4 so this bit is
permanently set to 0
4.8
TX_FDX
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
4.7
TX_HDX
1, RW
100BASE-TX Support
1 = 100BASE-TX half duplex is supported by the local
device
0 = 100BASE-TX half duplex is not supported
4.6
10_FDX
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
4.5
10_HDX
1, RW
10BASE-T Support
1 = 10BASE-T half duplex is supported by the local device
0 = 10BASE-T half duplex is not supported
