D I/O
Device Reset. Open-drain output of internal POR and VDD monitor.
An external source can initiate a system reset by driving this pin low
for at least 15 s.
LINK
3*
—
D Out
Link LED. Push-pull output driven high when valid 10BASE-T link
pulses are detected (Link Good) and driven low when valid
10BASE-T link pulses are not detected (Link Fail).
ACT
2*

D Out
Activity LED. Push-pull output driven high for 50 ms when any
packet is transmitted or received and driven low all other times.
LA

1*
D Out
Link or Activity LED. Push-pull output driven high when valid link
pulses are detected (Link Good) and driven low otherwise (Link
Fail). The output is toggled for each packet transmitted or received,
then returns to its original state after 50 ms.
