†
PCI Parity Error asserted when a PCI parity error is detected — between the PCI_PAR and
associated information on the PCI_AD bus and PCI_CBE_N — during all PCI transactions, except for
Special Cycles. The agent receiving data will drive this signal.
When this interface/signal is enabled and is not being used in a system design, the interface/signal
should be pulled high with a 10-KΩ resistor. When this interface is disabled via the PCI soft fuse
(refer to Expansion Bus Controller chapter of the Intel
Network Processors Developer’s Manual) and is not being used in a system design, this interface/
signal is not required for any connection.
PCI System Error asserted when a parity error occurs on special cycles or any other error that will
cause the PCI bus not to function properly. This signal can function as an input or an open drain
output.
When this interface/signal is enabled and is not being used in a system design, the interface/signal
should be pulled high with a 10-KΩ resistor. When this interface is disabled via the PCI soft fuse
(refer to Expansion Bus Controller chapter of the Intel
Network Processors Developer’s Manual) and is not being used in a system design, this interface/
signal is not required for any connection.
PCI Device Select:
When this interface/signal is enabled and is not being used in a system design, the interface/signal
should be pulled high with a 10-KΩ resistor. When this interface is disabled via the PCI soft fuse
(refer to Expansion Bus Controller chapter of the Intel
Network Processors Developer’s Manual) and is not being used in a system design, this interface/
signal is not required for any connection.
PCI Initialization Device Select is a chip select during configuration reads and writes.
When this interface/signal is enabled and is not being used in a system design, the interface/signal
should be pulled high with a 10-KΩ resistor. When this interface is disabled via the PCI soft fuse
(refer to Expansion Bus Controller chapter of the Intel
Network Processors Developer’s Manual) and is not being used in a system design, this interface/
signal is not required for any connection.
PCI arbitration request: Used by the internal PCI arbiter to allow an agent to request the PCI bus.
When this interface/signal is enabled and is not being used in a system design, the interface/signal
should be pulled high with a 10-KΩ resistor. When this interface is disabled via the PCI soft fuse
(refer to Expansion Bus Controller chapter of the Intel
Network Processors Developer’s Manual) and is not being used in a system design, this interface/
signal is not required for any connection.
