The PCI bus operates at the CLKIN frequency. All timings are relative to the input clock, CLKIN.
All PCI signals are bused signals except for PCI_GNT[3:0] and PCI_REQ[3:0]. These signals are defined as point-to-point
signals by the PCI Specification.
The 66-MHz parameters are only guaranteed when the 66-MHz PCI pad slew rates are selected. Likewise, the 33-MHz
parameters are only guaranteed when the 33-MHz PCI pad slew rates are selected.
