General-purpose I/O port 5 bit 0. (Default after strapping)
During VSB power reset (RSMRST#), this pin is pulled high
internally and is defined as VID transition voltage level (GTL or
TTL), and the value is shown at CR2C bit 3. The PCB layout
should reserve space for a 1-kΩ resistor to pull down this pin if
TTL is the selected VID level.
Watchdog Timer output signal.
General-purpose I/O port 5 bit 1.
Resume reset signal output.
General-purpose I/O port 5 bit 2.
System S3 state input.
General-purpose I/O port 5 bit 3.
Power supply on-off output.
General-purpose I/O port 5 bit 4.
This pin generates the PWROK signal while 3VCC comes in.
General-purpose I/O port 5 bit 5. (Default)
During VSB power reset (RSMRST#), this pin is pulled down
internally and is defined as EN_ACPI (enabling particular ACPI
functions), which provides the value for CR2C bit 4 (EN_ACPI).
The PCB layout should reserve space for a 1-kΩ resistor to pull
down this pin to ensure successful disabling of particular ACPI
functions, and a 1-kΩ resistor is recommended to pull the pin up
if wish to enable particular ACPI functions.
Suspended LED output.

resistor.
General-purpose I/O port 5 bit 7.
Panel Switch Output. This signal is used to wake-up the system
from S3/S5 state.
