2.25 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.
NOTE: SLP_LAN# may also be configured by Intel
®
ME FW in Sx/Moff. Please refer to SLP_LAN#/
GPIO29 signal description for details.
Table 2-25. Manageability Signals
Name Type Description
SUSWARN# /
SUSPWRDNACK /
GPIO30 (Mobile
Only)
I/O
Used by Intel
®
ME as either SUSWARN# in Deep S4/S5 state
supported platforms or as SUSPWRDNACK in non Deep S4/S5
state supported platforms.
NOTE: This signal is in the Suspend power well.
ACPRESENT /
GPIO31 (Mobile
Only)
I/O
Input signal from the Embedded Controller (EC) on Mobile
systems to indicate AC power source or the system battery.
Active High indicates AC power.
NOTE: This signal is in the Deep S4/S5 power well.
SATA5GP / GPIO49
/ TEMP_ALERT#
I/O
Used as an alert (active low) to indicate to the external
controller (such as EC or SIO) that temperatures are out of
range for the PCH or Graphics/Memory Controller or the
processor core.
NOTE: This signal is in the Core power well.
GPIO24 /
PROC_MISSING
(Desktop Only)
I/O
Used to indicate Processor Missing to the Intel Management
Engine.
NOTE: This signal is in the Suspend power well.
