VDD_GD
INt
Active-High of this signal indicates VDD voltage is valid.
This signal is usually connected to the power-good output
of the PWM for CPU core voltage
2
VLDT_SEN
INa
This pin is used to detect the ClawHammer VLDT (1.2V)
power or power-good signal.
3
VDDA_SEN
INa
This pin is used to detect the ClawHammer VDDA (2.5V)
power or power-good signal.
4
VDIMM_SEN
INa
This pin is used to detect the VDIMM (2.5V/1.8V) power or
power-good signal.
5
SB_PSON#
INt
Active low. This signal is connected to the PSON# signal
from the SB or Super I/O to control the on/off of ATX power
supply.
6
ACPI_S3
INt
Active high. This signal indicates that the system is in S3
state.
7
ATX_PWRGD
INt
Active-High of this signal indicates all of the voltage from
the ATX power supply is valid.

OD70
Active low. This pin is used to control the on/off of ATX
power supply. Active-Low of this signal will turn on the ATX
power supply. This pin is open-drain output and should be
pulled-up via a resistor to 5VSB externally.
Active low. This function is panel reset botton input with
de-bounce circuit.
Active high. This signal is connected to the Claw Hammer
to indicate all system powers are valid. This pin is opendrain output and should be pulled-up externally via a
resistor to 2.5V.
