BIT NAME
Collision Test

R/W
BIT DESCRIPTION
1 = Enable COL test. If Collision Test is a logic 1 and transmit data is
sent to the PHY, the IP100 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 IP100 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 IP100 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.
