Description

LED1 output: Programmable LED1 output

Config mode: The voltage on this pin is sampled and latched during the

power-up/reset process to determine the value of PHYAD[0]. See the Strap-In

Options - KSZ9031RNX section for details.

PME_N output: Programmable PME_N output (pin option 1). This pin function

requires an external pull-up resistor to DVDDH (digital VDD_I/O) in a range

from 1.0 kΩ to 4.7 kΩ. When asserted low, this pin signals that a WOL event

has occurred.

This pin is not an open-drain for all operating modes.

The LED1 pin is programmed by the LED_MODE strapping option (Pin 41),

and is defined as follows:

For tri-color dual-LED mode, LED1 works in conjunction with LED2 (Pin 15) to

indicate 10 Mbps link and activity.
