Manageability Signals

The following signals can be optionally used by Intel Management Engine supported
applications and appropriately configured by Intel Management Engine firmware. When
configured and used as a manageability function, the associated host GPIO
functionality is no longer available. If the manageability function is not used in a
platform, the signal can be used as a host General Purpose I/O or a native function.

Used by Intel ME as either SUSWARN# in Deep S4/S5 state
supported platforms or as SUSPWRDNACK in non Deep S4/S5
I/O
state supported platforms.
NOTE: This signal is in the Suspend power well.
Input signal from the Embedded Controller (EC) on Mobile
systems to indicate AC power source or the system battery.
I/O
Active High indicates AC power.
NOTE: This signal is in the Deep S4/S5 power well.
Used as an alert (active low) to indicate to the external
controller (such as EC or SIO) that temperatures are out of
I/O range for the PCH or Graphics/Memory Controller or the
processor core.
NOTE: This signal is in the Core power well.
Used to indicate Processor Missing to the Intel Management
I/O Engine.
NOTE: This signal is in the Suspend power well.
