1 -> software reset, reset in process
0 -> normal operation
This bit, which is self-clearing, returns 1 until the reset process
is complete. After this reset the configuration is not re-strapped.
1 -> Loop-back enabled
0 -> Normal operation
Local loop-back passes data from transmitting to receiving
serial conversion analog logic.
1 -> 100 Mb/s
0 -> 10 Mb/s
Ignored if auto-negotiation is enabled
1 -> Auto-negotiation is enabled
0 -> Auto-negotiation is disabled
Bits 8 and 13 of this register are ignored if this bit is set high.
Not available in FX-mode (auto-negotiation always disabled)
1 -> Power down
0 -> Normal operation
1 -> Isolates the core from the MII, with the exception of the
serial management
0 -> Normal operation.
When this bit is set to ‘1’, related pad outputs are forced to tri-
state, inputs are ignored.
MII isolate mode can be activated at initialization by strapping
00000 on physical address.
1 -> Restarts Auto-negotiation process (ignored if Auto-
negotiation is disabled)
0 -> Normal operation
1 -> full-duplex operation
0 -> Half-duplex operation
Ignored if auto-negotiation is enabled
