1 = PHY is capable of Next Page exchanges
0 = PHY is not capable of Next Page exchanges
Write as 0, ignore on read
1 = Remote fault.
0 = No remote fault.
Write as 0, ignore on read
Pause operation defined in Clause 40 and 27
Pause operation defined per IEEE 802.3x
standard
1 = 100BASE-T4 capability is available.
0 = 100BASE-T4 capability is not available.
(The LXT973 Transceiver does not support
100BASE-T4 but allows this bit to be set to
advertise in the auto-negotiation sequence for
100BASE-T4 operation. An external 100BASE-
T4 transceiver may be switched in, if this
capability is desired.)
1 = DTE is 100BASE-TX full-duplex capable.
0 = DTE is not 100BASE-TX full-duplex
capable.
1 = DTE is 100BASE-TX capable.
0 = DTE is not 100BASE-TX capable.
1 = DTE is 10BASE-T full-duplex capable.
0 = DTE is not 10BASE-T full-duplex capable.
1 = DTE is 10BASE-T capable.
0 = DTE is not 10BASE-T capable.
<00001> = IEEE 802.3
<00010> = IEEE 802.9 ISLAN-16T
<00000> = Reserved for future auto-negotiation
development
<11111> = Reserved for future auto-negotiation
development
Unspecified or reserved combinations should
not be transmitted.
Note: The selector field can be programmed to
any value. In order for auto-negotiation to
complete, the link partner’s received selector
field must match the value programmed in this
register.
