DESCRIPTION
100Base-T4 Capable:
This protocol is not available. Always 0 = Device does not perform 100Base-T4 mode.
100Base-TX Full Duplex Capable:
1 = Device able to perform 100Base-TX in full duplex mode
0 = Device not able to perform 100Base-TX in full duplex mode
100Base-TX Half Duplex Capable:
1 = Device able to perform 100Base-TX in half duplex mode
0 = Device not able to perform 100Base-TX in half duplex mode
10Base-T Full Duplex Capable:
1 = Device able to perform 10Base-T in full duplex mode
0 = Device not able to perform 10Base-T in full duplex mode
10Base-T Half Duplex Capable:
1 = Device able to perform 10Base-T in half duplex mode
0 = Device not able to perform 10Base-T in half duplex mode
RESERVED: Write as 0, read as 0
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 = Device will not perform management transaction with preambles suppressed
Auto-Negotiation Complete:
1 = Auto-Negotiation process complete
0 = Auto-Negotiation process not complete (either still in process, disabled, or reset)
Remote Fault:
1 = Remote Fault condition detected (cleared on read or by reset). Fault criteria: Far End Fault
Indication or notification from Link Partner of Remote Fault.
0 = No remote fault condition detected
Auto Negotiation Ability:
1 = Device is able to perform Auto-Negotiation
0 = Device is not able to perform Auto-Negotiation
Link Status:
1 = Valid link established (for either 10 or 100Mbs operation)
0 = Link not established
Jabber Detect: This bit only has meaning in 10Mbs mode.
1 = Jabber condition detected
0 = No Jabber. condition detected
This bit is implemented with a latching function, such that the occurrence 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.
Extended Capability:
1 = Extended register capabilities
0 = Basic register set capabilities only
