This bit sets the status and control registers of the PHY(register
0062-0074H) in a default state. This bit is self-clearing. 1 = software
reset; 0 = normal operation.
Reserved
This bit sets the network speed. 1 = 100Mbps; 0 = 10Mbps. This bit‘s
initial value comes from 93C46.
This bit enables/disables the NWay auto-negotiation function. Set to
1 to enable auto-negotiation, bit13 will be ignored.
Set to 0 disables auto-negotiation, bit13 and bit8 will determine the
link speed and the data transfer mode, respectively. This bit‘s initial
value comes from 93C46.
Reserved
This bit allows the NWay auto-negotiation function to be reset.
1 = re-start auto-negotiation; 0 = normal operation.
This bit sets the duplex mode. 1 = full-duplex; 0 = normal operation.
This bit‘s initial value comes from 93C46.
If bit12 = 1, read = status write = register value.
If bit12 = 0, read = write = register value.
