Parallel Detect Mode
Write a 1 to this bit to add Parallel Detect mode. This will
allow auto-switching to work when auto-negotiation is off
while the other device has it on.
Auto Switching
Write a 1 to this bit to enable auto switching.
MDI State
Indicates state of the MDI pair or force configuration:
1 = MDIX (cross over)
0 = MDI
When AUTO_SW is a 1, this bit will only be readable.
When AUTO_SW is a 0, this bit can be written to set the
configuration.
Auto-Switch Completion
Indicates completion of auto-switch sequence.
1 = Sequence completed
0 = Sequence in progress or auto-switch is disabled.
Write initial pattern seed for switching algorithm. Initial
seed will directly affect attempts [9,8,5,4] respectively to
written bits [3:0]. Setting to [0000] will result in device
using its own seed of [0101].
