Description
When Auto MDI/MDI-X is disabled,
0 =
1 =
1 = disable MDI/MDIX
0 = enable MDI/MDIX
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
This bit has the same definition as register 1.5.
1 = flow control capable
0 = no flow control
1 = PHY in isolate mode
0 = not isolated
[000] = still in auto-negotiation
[001] = 10BASE-T half duplex
[010] = 100BASE-TX half duplex
[011] = default
[101] = 10BASE-T full duplex
[110] = 100BASE-TX full duplex
[111] = PHY/MII isolate
1 = enable SQE test
0 = disable
1 = disable scrambler
0 = enable
