Unused
7
PD_MODE
R/W
1
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.
6
AUTO_SW
R/W
1
Auto Switching
Write a 1 to this bit to enable auto switching.
5
MDIX
R/W
0
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.
4
MDIX_CM
R
0
Auto-Switch Completion
Indicates completion of auto-switch sequence.
1 = Sequence completed
0 = Sequence in progress or auto-switch is disabled.
3:0
MDIX_SD
R/W
<0000> MDIX Seed
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].
