NWAY Configuration Register : NWAYC (Reg 30h), R/W, default=84h
Bit

Description
Full Duplex Mode: Set 1 to force the full duplex mode. The default is 0, meaning
the half duplex mode. This bit is meaningful only if ANE = 0
Port Select 100/10 bit : Default is 0, meaning the 10 Base-T mode.
Autonegotiation Enable: Set to enable the NWAY function. Default is set. ANS[2:0]
should be written 001 to restart the autonegotiation sequence after ANE is set.
Autonegotiation status bits: Read only for the NWAY status, except when write
001 will restart the autonegotiation sequence. The MSB is the Reg30h.5 bit when
Nway settles down in one network mode, one bit of Reg31.4~Reg 31.7 will be set
to indicate the chosen network mode.
Autonegotiation Arbitration State, arbitration states are defined
000 = Autonegotiation disable
001 = Transmit disable
010 = ability detect
011 = Acknowledge detect
100 = Complete acknowledge detect
101 = FLP link good; autonegotiation complete
110 = Link check
Reserved
Link Test Enable : Default is high, meaning the link check is always enabled.
Reset forces a good link in the 10 Base-T mode for the testing purpose.

Description
Physical Link Status of 10 Mbps TP : Set for a good link in 10 Base-T.
Physical Link Status of 100 Mbps TP : Set for a good link in 100 Base-TX.
Link Partner NWAY Status : 1 to indicate the link partner is capable of NWAY
support. Reset for the non-NWAY link partner.
Auto-negotiation Completion : Set to indicate that a normal NWAY state machine
completion. Reset for incomplete state.
NWAY 100 TX Full_duplex Mode : Set to indicate NWAY is settled down in the
100 TX full duplex mode.
NWAY 100 TX Half_dulpex Mode : Set to indicate NWAY is settled down in the
100 Base-T half duplex mode.
NWAY 10 TX Full_duplex Mode : Set to indicate NWAY is settled down in the 10
Base-T full duplex mode.
NWAY 10 TX Half_duplex Mode : Set to indicate NWAY is settled down in the 10
Base-T half duplex mode.
