Description
1.15
100BASE-T4
0,RO/P
100BASE-T4 Capable:
1=NetPHY-1 device is able to perform in 100BASE-T4 mode.
0=NetPHY-1 device is not able to perform in 100BASE-T4 mode.
1.14
100BASE-TX
Full Duplex
1,RO/P
100BASE-TX Full Duplex Capable:
1=NetPHY-1 device is able to perform 100BASE-TX in Full Duplex mode.
0=NetPHY-1 device is not able to perform 100BASE-TX in Full Duplex
mode.
1.13
100BASE-TX
Half Duplex
1,RO/P
100BASE-TX Half Duplex Capable:
1=NetPHY-1 device is able to perform 100BASE-TX in Half Duplex mode.
0=NetPHY-1 device is not able to perform 100BASE-TX in Half Duplex
mode.
1.12
10BASE-T
Full Duplex
1,RO/P
10BASE-T Full Duplex Capable:
1=NetPHY-1 device is able to perform 10BASE-T in Full Duplex mode.
0=NetPHY-1 device is not able to perform 10BASE-T in Full Duplex mode.
1.11
10BASE-T
Half Duplex
1,RO/P
10BASE-T Half Duplex Capable:
1=NetPHY-1 device is able to perform 10BASE-T in Half Duplex mode.
0=NetPHY-1 device is not able to perform 10BASE-T in Half Duplex mode.
1.10-1.7
Reserved
0,RO
Reserved:
Write as 0, ignore on read.
1.6
MF Preamble
Suppression
0,RO
MII Frame Preamble Suppression:
1=PHY will accept management frames with preamble suppressed.
0=PHY will not accept management frames with preamble suppressed.
1.5
Auto-Negotiation
Complete
0,RO
Auto-Negotiation Complete:
1=Auto-Negotiation process completed.
0=Auto-Negotiation process not completed.
1.4
Remote Fault
0,
RO/LH
Remote Fault:
1= Remote fault condition detected (cleared on read or by a chip reset).
Fault criteria and detection method is NetPHY-1 device implementation
specific. This bit will set after the RF bit in the ANLPAR (bit 13, register
address 05) is set.
0= No remote fault condition detected.
1.3
Auto-Negotiation
Ability
1,RO/P
Auto Configuration Ability:
1=NetPHY-1 device able to perform Auto-Negotiation.
0=NetPHY-1 device not able to perform Auto-Negotiation.
1.2
Link Status
0,RO/LL
Link Status:
1=Valid link established (for either 10 Mbps or 100 Mbps operation).
0=Link not established.
The link status bit is implemented with a latching function, so that the
occurrence of a link failure condition causes the Link Status bit to be
cleared and remain cleared until it is read via the management interface.
