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.

Should be pulled high with a 10-KΩ resistor when not being utilized in the system.
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.
