1 = 100BASE-TX with half-duplex.
RO
0 = No TX half-duplex ability.
Tied to 0 indicates no 10BASE-T full-duplex support.
RO
1 = 10BASE-T with half-duplex.
0 = No 10BASE-T half-duplex ability.
1 = Auto-negotiate process completed, indicates Reg. 4, 5, 6 are
valid.
0 = Auto-negotiate process not completed.
1 = Remote fault condition detected.
0 = No remote fault.
After this bit is set, it remains set until it is cleared by reading
register 1 via MDC/MDIO interface.
1 = Able to perform auto-negotiation function, its value is
determined by ANEGA pin.
0 = Unable to perform auto-negotiation function.
1 = Link is established. If AC206 link fails, this bit becomes
cleared and remains cleared until register is read via MDC/MDIO
interface.
0 = Link is down, or has been dropped.
1 = Jabber condition detect.
0 = No Jabber condition detected.
1 = Extended register capable. This bit is tied permanently to
one.
