100Base-T4 1 = enable 100Base-T4 support

0 = suppress 100Base-T4 support

100Base_TX_ 1 = enable 100Base-TX full duplex support

FD

0 = suppress 100Base-TX full duplex support

100BASE_TX_ 1 = enable 100Base-TX half duplex support

HD

0 = suppress 100Base-TX half duplex support

10Base_T_FD 1 = enable 10Base-T full duplex support

MF Preamble The RTL8201BL will accept management frames

Suppression with preamble suppressed. The RTL8201BL accepts

management frames without preamble. A Minimum

of 32 preamble bits are required for the first SMI

read/write transaction after reset. One idle bit is

required between any two management transactions

as per IEEE802.3u specifications

Auto

1 = auto-negotiation process completed

Negotiation 0 = auto-negotiation process not completed

Complete

Remote Fault 1 = remote fault condition detected (cleared on read)

0 = no remote fault condition detected

When in 100Base-FX mode, this bit means an

in-band signal Far-End-Fault is detected. Refer to

Section 7.11.

Auto

1 = Link had not been experienced fail state

Negotiation 0 = Link had been experienced fail state

Link Status 1 = valid link established

0 = no valid link established

Jabber Detect 1 = jabber condition detected

0 = no jabber condition detected

Extended 1 = extended register capability

Capability 0 = basic register capability only
