PCI Power Management Event
Note:
PCI Bus Power Good: This pin is used to sense the
presence of PCI bus power during the D3 power
management state.
Note:
PCI Auxiliary Voltage Sense: This pin is used to sense
the presence of a 3.3V auxiliary supply in order to define
the PME support available.
Note:
This pin is an open drain output.
This pin is a tri-state output.
This pin is an open drain output.
This pin is pulled low through an internal pull-
down resistor
