Description
When Auto MDI/MDI-X is disabled,
Mode
RW
0 = Transmit on TX+/- (pins 41,40)
Receive on RX+/- (pins 33,32)
1 = Transmit on RX+/- (pins 33,32)
Receive on TX+/- (pins 41,40)
1 = disable MDI/MDIX
RW
0 = enable MDI/MDIX
1 = presence of signal on RX+/- analog wire RO
pair
0 = no signal detected on RX+/-
1 = force link pass
RW
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
RW
0 = disable
1 = interrupt pin active high
RW
0 = active low
1 = enable jabber counter
RW
0 = disable
1 = auto-negotiation complete
RO
0 = not complete
This bit has the same definition as register 1.5.
1 = flow control capable
RO
0 = no flow control
1 = PHY in isolate mode
RO
0 = not isolated
[000] = still in auto-negotiation
RO
[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
