PCI bus parity
PCI parity error
PCI power management event. This
terminal may be used to detect PME
events from a PCI device on the
secondary bus.
Note: The PME input buffer has
hysteresis.
PCI request inputs. These signals are
used for arbitration on the secondary PCI
bus when an external arbiter is not used.
REQ0 is used as the GNT for the bridge
when an external arbiter is used.
PCI reset. This terminal is an output to
the secondary PCI bus.
