Device Reset. Open-drain output of internal POR and V
An external source can initiate a system reset by driving this pin low
for at least 15 µs.
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).
Activity LED. Push-pull output driven high for 50 ms when any
packet is transmitted or received and driven low all other times.
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.
Crystal Input. This pin is the return for the external oscillator driver.
This pin can be overdriven by an external CMOS clock.
Crystal Output. This pin is the excitation driver for a quartz crystal.
10BASE-T Transmit, Differential Output (Positive).
10BASE-T Transmit, Differential Output (Negative).
10BASE-T Receive, Differential Input (Positive).
10BASE-T Receive, Differential Input (Negative).
Motorola Bus Format Enable. This pin should be tied directly to V
for Motorola bus format or directly to GND for Intel bus format.
Multiplexed Bus Enable. This pin should be tied directly to V
multiplexed bus mode or directly to GND for non-multiplexed bus
mode.
Interrupt Service Request. This pin provides notification to the host.
