Type Description
3.3V To wakeup the system,
In this input must be pulled
to GND.
3.3V Indicates a watchdog
Out timeout event with a high
level. Cleared with a
reset and at power-on.
3.3V Low = system is in
Out suspend state S3/S4/S5
(ACPI).
3.3V Low = system is in
Out suspend state S4/S5
(ACPI).
3.3V General purpose I/O pin.
I/O
3.3V To reset the system, this
In input must be pulled to
GND.
3.3V Goes low during the reset
Out phase and stays at high
in the running phase.
3.3V High = feedback from the
In external power supplies,
that the voltages are in
the valid ranges.
3.3V High = power supply on
Out the baseboard is
switched on.
3.3V To activate this signal,
In the PWR_BTN# must be
pulled to GND.
3.3V Low = onmodule BIOs is
In disabled, an external
BIOS may be connected
over LPC.
3.3V Connect to the SuperIO's
In KBC to switch between
real and protected mode.
