Description
3. For GPIOs where GPIO versus Native Mode is configured using SPI Soft Strap, the corresponding GPIO_USE_SEL bits for
these GPIOs have no effect. The GPIO_USE_SEL bits for these GPIOs may change to reflect the Soft-Strap configuration
even though GPIO Lockdown Enable (GLE) bit is set. For signals that have Native defaults, these signals must be configured
by using SPI Soft Strap.
4. The functionality that is multiplexed with the GPIO may not be used in desktop configuration.
5. In a ME disabled system, GPIO31 may be used as ACPRESENT from the EC.
