Description
0 = Disable auto-negotiation process
1 = Enable auto-negotiation process
This register bit must be enabled for
1000BASE-T operation.
0 = Normal operation
1 = Power-down
0 =
1 = Electrically isolate PHY from GMII
0 = Normal operation
1 = Restart auto-negotiation process
0 = Half-duplex mode
1 = Full-duplex mode
0 = Disable COL signal test
1 = Enable COL signal test
This register bit is ignored unless loopback is
enabled (Register bit 0.14 = 1)
0.6 (Speed<1>) 0.13 (Speed<0>)
00 = 10 Mbps
01 = 100 Mbps
10 = 1000 Mbps (manual mode now allowed)
11 = Reserved
