Description
1 = presence of signal on RX+/-
analog wire pair
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
1 = interrupt pin active high
0 = active low
1 = enable jabber counter
0 = disable
1 = auto-negotiation complete
0 = not complete
1 = flow control capable
0 = no flow control
1 = PHY in isolate mode
0 = not isolated
[000] = still in auto-negotiation
[001] = 10BaseT half duplex
[010] = 100BaseTX half duplex
[011] = default
[101] = 10BaseT full duplex
[110] = 100BaseTX full duplex
[111] = PHY/MII isolate
1 = enable SQE test
0 = disable
1 = disable scrambler
0 = enable
