0 1.4
-- RO Remote fault
0
LH 1 = remote fault detected
0 = not remote fault detected
When read as logic 1, indicates that IP178C/IP178CH has

0 1.3
-- RO Auto-Negotiation Ability
1
1 = Auto-Negotiation capable
0 = not Auto-Negotiation capable
When read as logic 1, indicates that IP178C/IP178CH has the

operation mode.
0 1.2
-- RO Link Status
0

-- RO Jabber Detect
0
LH 1 = jabber condition detected
0 = no jabber condition detected
When read as logic 1, indicates that IP178C/IP178CH has
detected a jabber condition. This bit is always 0 for 100 Mbps
operation and is cleared after IP178C/IP178CH reset. This bit
is set until jabber condition is cleared and reading the
