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-
ping Options - KSZ9031MNX 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 55),
and is defined as follows:

For tri-color dual-LED mode, LED1 works in conjunction with LED2 (Pin 17) to
indicate 10 Mbps link and activity.
