STE100P

10/29

ANC

Auto-Negotiation Completed.

0: Auto-Negotiation process is not completed .

1: Auto-Negotiation process is completed.

0RO

Result of remote fault detection.

0: No remote fault condition detected.

1: Remote fault condition detected.

This bit is set when the Link Partner transmits a remote fault

condition (PR5 bit 13 = 1).

RO/LH*

Auto-Negotiation ability.

Always 1, since STE100P has the Auto-Negotiation ability.

1RO

LINK

Link status.

0: a failure link condition occurred. Read to set.

1: a valid link is established.

RO/LL*

JAB

Jabber detection.

1: jabber condition is detected (10Base-T only).

RO/LH*

EXT

Extended register supporting.

Always 1, since STE100P supports extended register

1RO

LL* = Latching Low and clear by read. LH* = Latching High and clear by read.

15~0

PHYID1

Part one of PHY Identifier.

Assigned to the 3rd to 18th bits of the Organizationally Unique

Identifier (OUI). (The ST OUI is 0080E1 hex).

1C04h

PR3- PID2, PHY Identifier 2

15~10

PHYID2

Part two of PHY Identifier.

Assigned to the 19th to 24th bits of the Organizationally Unique

Identifier (OUI).

3~0

REV

Revision number of STE100P.

Four bits manufacture’s revision number.

0001b

PR4- ANA, Auto-Negotiation Advertisement

NXTPG

Next Page ability.

Always 0: since STE100P does not provide next page ability.

0RO

Reserved

Remote Fault function.

1: with remote fault function.

R/W

12,11

---

Reserved

Flow Control function Ability.

1:supports PAUSE operation of flow control for full duplex link.

R/W

100BASE-T4 Ability.

Always 0: since STE100P doesn’t have 100BASE-T4 ability.
