Bit
Bit Name
Default
Description
15
100BASE-T4
0, RO/P
100BASE-T4 Capable:
0 = Device not able to perform 100BASE-T4 mode.
14
100BASE-TX
Full Duplex
1, RO/P
100BASE-TX Full Duplex Capable:
1 = Device able to perform 100BASE-TX in full duplex mode.
13
100BASE-TX
Half Duplex
1, RO/P
100BASE-TX Half Duplex Capable:
1 = Device able to perform 100BASE-TX in half duplex mode.
12
10BASE-T
Full Duplex
1, RO/P
10BASE-T Full Duplex Capable:
1 = Device able to perform 10BASE-T in full duplex mode.
11
10BASE-T
Half Duplex
1, RO/P
10BASE-T Half Duplex Capable:
1 = Device able to perform 10BASE-T in half duplex mode.
10:7
RESERVED
0, RO
RESERVED: Write as 0, read as 0.
6
MF Preamble
Suppression
1, RO/P
Preamble suppression Capable:
1 = Device able to perform management transaction with preamble
suppressed, 32-bits of preamble needed only once after reset, invalid
opcode or invalid turnaround.
0 = Normal management operation.
5
Auto-Negotiation Com-
plete
0, RO
Auto-Negotiation Complete:
1 = Auto-Negotiation process complete.
0 = Auto-Negotiation process not complete.
4
Remote Fault
0, RO/LH
Remote Fault:
1 = Remote Fault condition detected (cleared on read or by reset).
Fault criteria: Far End Fault Indication or notification from Link Part-
ner of Remote Fault.
0 = No remote fault condition detected.
3
Auto-Negotiation Abili-
ty
1, RO/P
Auto Negotiation Ability:
1 = Device is able to perform Auto-Negotiation.
0 = Device is not able to perform Auto-Negotiation.
2
Link Status
0, RO/LL
Link Status:
1 = Valid link established (for either 10 or 100 Mb/s operation).
0 = Link not established.
The criteria for link validity is implementation specific. The occurrence
of a link failure condition will causes the Link Status bit to clear. Once
cleared, this bit may only be set by establishing a good link condition
and a read via the management interface.
1
Jabber Detect
0, RO/LH
Jabber Detect: This bit only has meaning in 10 Mb/s mode.
1 = Jabber condition detected.
0 = No Jabber.
This bit is implemented with a latching function, such that the occur-
rence of a jabber condition causes it to set until it is cleared by a read
to this register by the management interface or by a reset.
0
Extended Capability
1, RO/P
Extended Capability:
1 = Extended register capabilities.
0 = Basic register set capabilities only.
