Description

Default

Status register

4~0

1.15

100Base-T4 capable

1 = 100Base-T4 capable

0 = not 100Base-T4 capable

IP175C/IP175CH does not support 100Base-T4. This bit is

fixed to be 0.

4~0

1.14

100Base-X full duplex Capable

1 = 100Base-X full duplex capable

0 = not 100Base-X full duplex capable

4~0

1.13

100Base-X half duplex Capable

1 = 100Base-X half duplex capable

0 = not 100Base-X half duplex capable

4~0

1.12

10Base-T full duplex Capable

1 = 10Base-T full duplex capable

0 = not 10Base-T full duplex capable

4~0

1.11

10Base-T half duplex Capable

1 = 10Base-T half duplex capable

0 = not 10Base-T half duplex capable

1.6

MF preamble Suppression

1 = preamble may be suppressed

0 = preamble always required

4~0

1.5

Auto-Negotiation Complete

1 = Auto-Negotiation complete

0 = Auto-Negotiation in progress

When read as logic 1, indicates that the Auto-Negotiation

process has been completed, and the contents of register 4

and 5 are valid. When read as logic 0, indicates that the

Auto-Negotiation process has not been completed, and the

contents

and

are

meaningless.

Auto-Negotiation is disabled (bit 0.12 set to logic 0), then this

bit will always read as logic 0.

4~0

1.4

Remote fault

1 = remote fault detected

0 = not remote fault detected

When read as logic 1, indicates that IP175C/IP175CH has

detected a remote fault condition. This bit is set until remote

fault condition gone and before reading the contents of the

4~0

1.3

Auto-Negotiation Ability

1 = Auto-Negotiation capable

0 = not Auto-Negotiation capable

When read as logic 1, indicates that IP175C/IP175CH has the

ability to perform Auto-Negotiation.
