This GPxx* can serve as GPIO or the Watchdog Timer output
signals.
This GPxx*** can serve as GPIO or Suspend-LED output
signals.
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
General-purpose I/O port 5 bit 5.
SLP_S5# input. (This pin function is both for UBE and UBF
version only)
General-purpose I/O port 3 bit 7
recommended to pull the pin up if wish to enable particular
ACPI functions. (This pin function is both for UBE and UBF
version only)
Suspended LED output.
Switch 3VSB power to memory when in S3 state. The default
is disabled while the particular ACPI functions are enabled.
The control bit is at Logical Device A, CR[E4h] bit 4. (This pin
function is both for UBE and UBF version only)
General-purpose I/O port 3 bit 1.
This pin generates the PWROK2 signal while 3VCC comes
in. (This pin function is both for UBE and UBF version only)
General-purpose I/O port 3 bit 0.
ATX power good input signal. It is connected to the PWROK
signal from the power supply for PWROK/PWROK2
generation. The default is enabled. (This pin function is both
for UBE and UBF version only)
General-purpose I/O port 3 bit 5.
Connect to the reset button. This pin has internal de-bounce
circuit whose de-bounce time is at least 32 mS. (This pin
function is both for UBE and UBF version only)
General-purpose I/O port 3 bit 6.
