Power and Ground Signals (Sheet 1 of 2)
NOTES:
1. GPIO[0:7], GPIO[16:21, 23], and GPIO[32:55] are in the core well.
2. GPIO[8:15] and GPIO[24:31] are in the suspend well.
3. Core-well GPIO are 5 V tolerant, except for GPIO[7:6] and [32:43].
4. Resume-well GPIO are not 5 V tolerant.
5. GPIO[56:57] pads are in the suspend well, the register bits are in the RTC well.

3.3 V supply for core well I/O buffers. This power may be shut off in S3, S4,
or S5 states.
1.5 V supply for core well logic. This power may be shut off in S3, S4, S5 or
S5 states.
1.5 V supply for Hub Interface 1.5 logic.
This power may be shut off in S3, S4, and S5 states.
Reference for 5 V tolerance on core well inputs. This power may be shut off
in S3, S4, S5 or G3 states.
3.3V reference voltage for PCI-X inputs
1.5V supply for Hub Interface PLL.
This power may be shut off in S3, S4, and S5 states.
Analog Input. Expected voltages are 350 mV for the Hub Interface 1.5
(Enhanced Hub Interface) Parallel Termination.
This power is shut off in S3, S4, S5 and 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.
1.5 V supply for resume well logic. This power is not expected to be shut off
unless the system is unplugged in desktop configurations.
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.
3.3 V (may drop to 2.0 V min. in G3 state) supply for the RTC well. This
power is not expected to be shut off unless the RTC battery is removed or
completely drained.
