Description
Remote fault definitions:
00 = No error, link okay
01 = Offline
10 = Link failure
11 = Auto-negotiation_Error
Write as 0, ignore on Read
Asym Pause. The ability to send pause frames.
Sym Pause. The ability to send and receive pause
frames.
Half-duplex

Write as 0, ignore on read
Description
Reserved
Write as 0, ignore on Read.
2
Write as 1, ignore on Read.
2
Write as 0, ignore on Read.
2
Write as 1, ignore on Read.
0 = Normal operation
1 = Enable padding of undersized packets
NOTE: Assertion of this bit results in the
automatic addition of a CRC to the
padded packet.
0 = Normal operation
1 = Enable automatic CRC appending
Enable auto-negotiation (used for fiber mode only)
to be performed by the hardware state machines
in the MAC.
The hardware auto-negotiation (AN) state
machine controls the config words transmitted
when this bit is set.
NOTE: In copper mode, this bit must be set to 0
(reserved).
Write as 0, ignore on Read.
