REM_FLT- Remote Fault Detect
‘1’ indicates a Remote Fault. Latches the ‘1’ condition and is cleared by reading this register or
resetting the PHY.
CAP_ANEG - AutoNegotiation Capable
Indicates the ability (‘1’) to perform ANEG or not (‘0’).
LINK - Link Status
A ‘1’ indicates a valid Link and a ‘0’ and invalid Link. The ‘0’ condition is latched until this register is
read.
JAB - Jabber Detect
Jabber condition detected when ‘1’ for 10Mbps. ‘1’ latched until this register is read or the PHY is reset.
Always ‘0’ for 100Mbps
EXREG - Extended Capability register
These two registers (offsets 2 and 3) provide a 32-bit value unique to the PHY.
This register control the values transmitted by the PHY to the remote partner when advertising its
abilities
‘1’ Indicates extended registers are implemented
