PCI ZQ line termination:
PCI_M66EN must be terminated accordingly.
PCI_IDSEL must be terminated to GND if it is a central function.
Unused AD/Control signals must be terminated per PCI specification.
For a 64-bit operation, PCI_REQ# must be sampled at assertion on the rising edge of
PCI_RST and can also be enabled via the PCI_IXP_PARAM register.
Loading guidelines:
— ZQ1 tied to V
— ZQ2 tied to V
— 66 MHz – four loads
— 33 MHz – eight loads
