This bit indicates the power state of 100BASE-TX
PHY unit.
1 = Power-Down
0 = Normal operation
This bit indicates 10BASE-T polarity.
1 = Reverse polarity
0 = Normal polarity
These bits are reserved and should be set to 0B.
This bit indicates the Auto-Negotiation result.
1 = 100 Mbps
0 = 10 Mbps
This bit indicates the Auto-Negotiation result.
1 = Full Duplex
0 = Half Duplex
1 = By-pass Scrambler
0 = Normal operations
1 = 4 bit to 5 bit by-pass
0 = Normal operation
1 = Force transmit H-pattern
0 = Normal operation
1 = Force 34 transmit pattern
0 = Normal operation
1 = 100BASE-TX link good
0 = Normal operation
This bit is reserved and should be set to 0b.
1 = Transmit Carrier Sense disabled
0 = Transmit Carrier Sense enabled
1 = Dynamic Power-Down disabled
0 = Dynamic Power-Down enabled (normal)
1 = Auto-Negotiation loopback
0 = Auto-Negotiation normal mode
1 = MDI Tri-state (transmit driver tri-states)
0 = Normal operation
1 = By-pass filter
0 = Normal filter operation
1 = Auto Polarity disabled
0 = Normal polarity operation
1 = 10BASE-T squelch test disable
0 = Normal squelch operation
