Signal Description
Power Supply.
4.75 to 5.25V. This supply is turned on only when the mechanical
switch on the power supply is turned on and the PWRON signal is conditioned high.
Power Supply.
Always available unless the mechanical switch of the power supply
is turned off. If the "soft-off" state is not implemented, then this pin can be
connected to VDD5.
Power Supply.
This pin should be connected to the same voltage as the CPU I/O
circuitry.
PCI Voltage.
3.3 or 5V.
