Duplicate of bit 1.5.
Inverted duplicate of bit 0.12.
1 = MDI/MDI-X crossover
performed internally.
1 = CD pairs are swapped.
1 = Polarity swap on pair A.
1 = Polarity swap on pair B.
1 = Polarity swap on pair C.
1 = Polarity swap on pair D.
1 = Full duplex.
0 = Half duplex.
00 = Speed is 10BASE-T.
01 = Speed is 100BASE-TX.
10 = Speed is 1000BASE-T.
11 = Reserved.
This is a super-sticky bit.
1 = Enabled. When enabled, all MII
register bits listed as sticky retain
their values during a software
reset.
0 = Disabled. When disabled, all
MII register bits listed as sticky
change to their default values
during a software reset.
Note that bits listed as super sticky
retain their values during a
software reset regardless of this
setting.
