BIT DESCRIPTION
1 = Enable COL test. If Collision Test is a logic 1 and transmit
data is sent to the PHY, the IP100A LF PHY will assert the
collision signal within 512 bit times (where 1 bit time = 100ns
for 10Mbps operation and 1 bit time = 10ns for 100Mbps
operation). When transmit data is removed, the IP100A LF
PHY will deassert the collision signal within 4 bit times.
0 = Normal operation.
Reserved for future use.

BIT DESCRIPTION
1 = PHY 100BASE-T4 capable.
0 = PHY not 100BASE-T4 capable.
1 = PHY 100BASE-X Half Duplex capable.
0 = PHY not 100BASE-X Half Duplex capable.
1 = PHY 100BASE-X Half Duplex capable.
0 = PHY not 100BASE-X Half Duplex capable.
1 = PHY 10BASE-T Full Duplex capable.
0 = PHY not 10BASE-T Full Duplex capable.
1 = PHY 10BASE-T Half Duplex capable.
0 = PHY not 10BASE-T Half Duplex capable.
Reserved for future use.
1 = Management preamble may be suppressed.
0 = Management preamble required.
1 = Auto-Negotiation complete.
0 = Auto-Negotiation not complete.
If Auto-Negotiation Complete is a logic 1, the auto-negotiation
process is complete and the contents of the Auto-Negotiation Link
Partner Ability and Auto-Negotiation Expansion registers are
valid. If Auto-Negotiation Complete is a logic 0, the
Auto-Negotiation process is not complete, and the contents of the
Auto-Negotiation Link Partner Ability and Auto-Negotiation
Expansion registers are undefined. If the Auto-Negotiation bit of
the Control Register is a logic 0, then Auto-Negotiation Complete
is always a logic 0.
1 = Remote Fault detected.
0 = Remote Fault not detected.
If Remote Fault is a logic 1, the IP100A LF has detected a remote
fault condition. Remote Fault will remain a logic 1 until the remote
fault condition no longer exists, and Remote Fault is read by the
host system.
