8.5 Auto-negotiation Advertisement Register (ANAR) – 04H

This register contains the advertised abilities of this DM9013 device as they will be transmitted to its link partner

during Auto-negotiation.

Bit

Bit Name

Default

Description

0,RO/P

Next page Indication

0 = No next page available

1 = Next page available

The DM9013 has no next page, so this bit is permanently set to 0

ACK

0,RO

Acknowledge

0 = Not acknowledged

1 = Link partner ability data reception acknowledged

The DM9013'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.

0, RW

Remote Fault

0 = No fault detected

1 = Local device senses a fault condition

12-11

Reserved

X, RW

Reserved

Write as 0, ignore on read

FCS

1, RW

Flow Control Support

0 = Controller chip doesn’t support flow control ability

1 = Controller chip supports flow control ability

0, RO/P

100BASE-T4 Support

0 = 100BASE-T4 is not supported

1 = 100BASE-T4 is supported by the local device

The DM9013 does not support 100BASE-T4 so this bit is

permanently set to 0

TX_FDX

1, RW

100BASE-TX Full Duplex Support

0 = 100BASE-TX full duplex is not supported

1 = 100BASE-TX full duplex is supported by the local device

TX_HDX

1, RW

100BASE-TX Support

0 = 100BASE-TX half duplex is not supported

1 = 100BASE-TX half duplex is supported by the local device

10_FDX

1, RW

10BASE-T Full Duplex Support

0 = 10BASE-T full duplex is not supported

1 = 10BASE-T full duplex is supported by the local device

10_HDX

1, RW

10BASE-T Support

0 = 10BASE-T half duplex is not supported

1 = 10BASE-T half duplex is supported by the local device

4-0

Selector

<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
