50uA (typical) internal pull-up. Unless otherwise noted in the pin description, internal pull-ups
are always enabled.

Power and Ground pin
Internal pull-up resistors prevent unconnected inputs from floating. Do not rely on
internal resistors to drive signals external to LAN9420/LAN9420i. When connected
to a load that must be pulled high, an external resistor must be added.
Internal pull-down resistors prevent unconnected inputs from floating. Do not rely
on internal resistors to drive signals external to LAN9420/LAN9420i. When
connected to a load that must be pulled low, an external resistor must be added.
