Description
Default R/W
This bit allows the PHY to isolate the medium

RW
independent interface. The PHY is disconnected from the
LAN Connect block on both the transmit and receive side.
0 = Normal operation
1 = Isolates internal medium independent interface
This bit restarts the Auto-Negotiation process and is self-
clearing.
0 = Normal operation
1 = Restart Auto-Negotiation process
0
RW
SC
This bit controls the duplex mode when Auto-Negotiation
is disabled. When Auto-Negotiation is enabled this bit is
read only and always equals 1b.
When the PHY is placed in Loopback mode, the behavior
of the PHY shall not be affected by the status of this bit.
0 = Half Duplex
1 = Full Duplex
0
RW/
RO
This bit is not used in the 82562ET and has a default
value of 1b. (If it is used in other devices, it forces a
collision in response to the assertion of the transmit
enable signal.)

10:7 Reserved
Description
This bit is reserved and should be set to 0b.
This bit enables 100BASE-TX full-duplex operation
and is dependent on ADV10. If ADV10 is active, the
default value is 0.
0 = PHY unable to perform full-duplex 100BASE-TX
1 = PHY able to perform full-duplex 100BASE-TX
This bit enables 100BASE-TX half-duplex operation
and is dependent on ADV10. If ADV10 is active, the
default value is 0.
0 = PHY unable to perform half-duplex 100BASE-TX
1 = PHY able to perform half-duplex 100BASE-TX
This bit enables 10BASE-T full duplex operation.
0 = PHY unable to perform full-duplex 10BASE-T
1 = PHY able to perform full-duplex 10BASE-T
This bit enables 10BASE-T half-duplex operation.
0 = PHY unable to perform half-duplex 10BASE-T
1 = PHY able to perform half-duplex 10BASE-T
These bits are reserved and should be set to 0000b.
