Description
0 = Far-End Fault not detected
1 = Far-End Fault detected
This bit applies to KSZ8041FTL fiber only.
0 = MDI
1 = MDI-X
0 = Normal mode
1 = Remote (analog) loop back is enable
0 = Micrel Auto MDI/MDI-X mode
1 = HP Auto MDI/MDI-X mode
When Auto MDI/MDI-X is disabled,
0 = MDI Mode
1 = MDI-X Mode
1 = Disable auto MDI/MDI-X
0 = Enable auto MDI/MDI-X
1 = Presence of signal on RX+/- analog wire
0 = No signal detected on RX+/-
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
If power saving mode is enabled and the cable
is disconnected, the RXC clock output (in MII
mode) is disabled. RXC clock is enabled after
the cable is connected and link is established.
1 = Interrupt pin active high
0 = Interrupt pin active low
1 = Enable jabber counter
0 = Disable jabber counter
1 = Auto-negotiation process completed
0 = Auto-negotiation process not completed
1 = Flow control capable
0 = No flow control capability
