This pin is a no-connect (NC) for LAN9500A/LAN9500Ai, but may be connected to VDD33A for
backward compatibility with LAN9500/LAN9500i.
For LAN9500A/LAN9500Ai this pin provides additional PME related functionality. Refer to the
respective pin descriptions and Section 6.0, "PME Operation," on page 112 for additional information.
