10/100Mbps Ethernet Fiber/Twisted Pair Media Converter with Local bus

Preliminary datasheet

DM9302-15-DS-P01

July 30, 2009

0 = Not acknowledged

The DM9302'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

1 = Local device senses a fault condition

0 = No fault detected

12-11

Reserved

X, RW

Reserved

Write as 0, ignore on read

FCS

1, 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 DM9302 does not support 100BASE-T4 so this bit is

permanently set to 0

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

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

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

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

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

8.6 Auto-negotiation Link Partner Ability Register (ANLPAR) – 05H

This register contains the advertised abilities of the link partner when received during Auto-negotiation.

Description

0, RO

Next Page Indication

1 = Link partner, next page available

0 = Link partner, no next page available

ACK

0, RO

Acknowledge

1 = Link partner ability data reception acknowledged

0 = Not acknowledged

The DM9302's auto-negotiation state machine will automatically

control this bit from the incoming FLP bursts. Software should not

attempt to write to this bit
