Description
1 = PHY in isolate mode
0 = PHY in normal operation
[000] = still in auto-negotiation
[001] = 10Base-T half-duplex
[010] = 100Base-TX half-duplex
[011] = reserved
[100] = reserved
[101] = 10Base-T full-duplex
[110] = 100Base-TX full-duplex
[111] = reserved
1 = HP Auto MDI/MDI-X mode
0 = Micrel Auto MDI/MDI-X mode
When Auto MDI/MDI-X is disabled,
1 = MDI-X Mode
0 = MDI Mode
1 = Disable auto MDI/MDI-X
0 = Enable auto MDI/MDI-X
1 = Force link pass
0 = Normal link operation
This bit bypasses the control logic and allow
transmitter to send pattern even if there is no
link.
1 = Enable power saving
0 = Disable power saving
1 = Interrupt pin active high
0 = Interrupt pin active low
1 = Enable jabber counter
0 = Disable jabber counter
