GPI[15:0] can be configured to cause a SMI# or SCI. Note that a GPI can be routed to
either an SMI# or an SCI, but not both.
Some GPIOs exist in the VccSus3_3 power plane. Care must be taken to make sure GPIO
signals are not driven high into powered-down planes. Some ICH8 GPIOs may be
connected to pins on devices that exist in the core well. If these GPIOs are outputs, there
is a danger that a loss of core power (PWROK low) or a Power Button Override event will
result in the Intel ICH8 driving a pin to a logic 1 to another device that is powered down.
The functionality that is multiplexed with the GPIO may not be used in desktop
configuration.
This GPIO is not capable of actively driving high. This GPIO is tristated as an output and an
external pull-up is needed to pull the signal high).
