INT10
0 = Not source of interrupt
1 = Transmitter Elastic Buffer Overflow
INT9
0 = Not source of interrupt
1 = Transmitter Elastic Buffer Underflow
INT8
0 = Not source of interrupt
1 = Idle Error Count Overflow
INT7
0 = Not source of interrupt
1 = ENERGYON generated
This bit is set when there is a “0” to “1” transition of the ENERGYON bit in
the 10/100 Mode Control/Status Register. This occurs when transitioning
from no energy detected to energy detected, or vice versa.
INT6
0 = Not source of interrupt
1 = Auto-Negotiation complete
INT5
0 = Not source of interrupt
1 = Remote Fault Detected
INT4
0 = Not source of interrupt
1 = Link Down (link status negated)
