DESCRIPTION
PCI-X Capability Pin: PI7C9X110 can be forced to PCI mode if PCIXCAP is tied
to ground with a capacitor (0.1uF) in parallel. If PCIXCAP is connected to ground
through a capacitor (0.1uF), PI7C9X110 will be in 133MHz PCI-X mode. If
PCIXCAP is connected to ground through a resistor (10K Ohm) with a capacitor
(0.1uF) in parallel, PI7C9X110 will be in 66MHz PCI-X mode.
PCIXCAP Pull-up driver: PI7C9X110 drives this pin for PCI-X mode detection.
