the signal is stable in its inactive state of the native functionality, immediately after reset
until it is initialized to GPIO functionality.
When the multiplexed GPIO is used as GPIO functionality, care should be taken to ensure
3.3 V supply for core well I/O buffers. This power may be shut off in S3, S4, S5
or G3 states.
1.05 V supply for core well logic. This power may be shut off in S3, S4, S5 or
G3 states.
1.5 V supply for Logic and I/O. This power may be shut off in S3, S4, S5 or G3
states.
1.5 V supply for Logic and I/O. This power may be shut off in S3, S4, S5 or G3
states.
Power supply for DMI. 1.25V or 1.5V depending on (G)MCH’s DMI voltage.
Reference for 5 V tolerance on core well inputs. This power may be shut off in
S3, S4, S5 or G3 states.
3.3 V supply for resume well I/O buffers. This power is not expected to be shut
off unless the system is unplugged in desktop configurations or the main
battery is removed or completely drained and AC power is not available in
mobile configurations.
1.5V supply for the resume well I/O. This power is not expected to be shut off
unless the system is unplugged in desktop configurations.
This voltage is generated internally (see
and these pins can be left as NC unless decoupling is required.
1.05 V supply for resume well logic. This power is not expected to be shut off
unless the system is unplugged in desktop configurations or the main battery is
removed or completely drained and AC power is not available in mobile
configurations.
This voltage is generated internally (see
and these pins can be left as NC unless decoupling is required.
Reference for 5 V tolerance on resume well inputs. This power is not expected
to be shut off unless the system is unplugged in desktop configurations or the
main battery is removed or completely drained and AC power is not available in
mobile configurations.
1.5V supply for integrated Gigabit LAN I/O buffers. This power can be turned
off if the integrated Gigabit LAN is not used. If the integrated Gigabit LAN is
used, the power is off in S3, S4, S5.
3.3V supply for integrated Gigabit LAN logic and I/O. This power can be turned
off if the integrated Gigabit LAN is not used. If the integrated Gigabit LAN is
used, the power is off in S3, S4, S5.
1.05V supply for Controller Link. This voltage may be generated internally (see
Section 2.26.1
1.05 V power supply when the integrated VRM is disabled. This pin can be left
as NC if the internal VRM is used unless decoupling is required.
