PCI arbitration request:
Should be pulled high with a 10-KΩ resistor, when the PCI bus is
not being utilized in the system.
PCI arbitration grant: Generated by the internal PCI arbiter to
allow an agent to claim control of the PCI bus.

PCI interrupt: Used to request an interrupt.
Should be pulled high with a 10-KΩ resistor when not being
utilized in the system.
PCI Clock: provides timing for all transactions on PCI. All PCI
signals — except INTA#, INTB#, INTC#, and INTD# — are
sampled on the rising edge of CLK and timing parameters are
defined with respect to this edge. The PCI clock rate can operate
at up to 66 MHz.
