1 = software reset. Bit is self-clearing. For best results,
1 = loopback mode,
0 = normal operation
1 = 100Mbps,
0 = 10Mbps.
Ignored if Auto Negotiation is enabled (0.12 = 1).
1 = enable auto-negotiate process
0 = disable auto-negotiate process
1 = General power down mode,
0 = normal operation
1 = electrical isolation of PHY from MII
0 = normal operation
1 = restart auto-negotiate process
0 = normal operation. Bit is self-clearing.
1 = Full duplex,
0 = Half duplex.
1 = enable COL test,
0 = disable COL test
Ignored if Auto Negotiation is enabled (0.12 = 1).
1 = T4 able,
0 = no T4 ability
1 = TX with full duplex,
0 = no TX full duplex ability
1 = TX with half duplex,
0 = no TX half duplex ability
1 = 10Mbps with full duplex
0 = no 10Mbps with full duplex ability
1 = 10Mbps with half duplex
0 = no 10Mbps with half duplex ability
1 = auto-negotiate process completed
0 = auto-negotiate process not completed
1 = remote fault condition detected
0 = no remote fault
