These status bits are valid only after resolved bit
17_0.11 equals 1b. The resolved bit is set when
auto-negotiation completes or is disabled.
11b = Reserved.
10b = 1000 Mb/s.
01b = 100 Mb/s.
00b = 10 Mb/s.
This status bit is valid only after resolved bit 17_0.11
equals 1b. The resolved bit is set when auto-
negotiation completes or is disabled.
1b = Full-duplex.
0b = Half-duplex.
1b = Page received.
0b = Page not received.
When Auto-Negotiation is not enabled 17_0.11
equals 1b. 1b = Resolved.
0b = Not resolved.
1b = Link up.
0b = Link down.
This is a reflection of the MAC pause resolution. This
bit is for information purposes and is not used by the
82583V. This status bit is valid only after resolved
bit 17_0.11 = 1b. The resolved bit is set when auto-
negotiation completes or is disabled.
1b = Transmit pause enabled.
0b = Transmit pause disable.
This is a reflection of the MAC pause resolution. This

1b = Receive pause enabled.
0b = Receive pause disabled.
Reserved, set to 0x0.
This status bit is valid only after resolved bit 17_0.11
equals 1b. The resolved bit is set when auto-
negotiation completes or is disabled. This bit is 0b or
1b depending on what is written to 16.6:5 in manual
configuration mode. Register 16.6:5 are updated
with a software reset.
1b = MDI-X.
0b = MDI.
1b = Downshift.
0b = No downshift.
1b = Sleep.
0b = Active.
1b = Copper link is up.
0b = Copper link is down.
