This signal is usually connected to the power-good output of the PWM for CPU core voltage This pin is used to detect the ClawHammer VLDT (1.2V) power or power-good signal. This pin is used to detect the ClawHammer VDDA (2.5V) power or power-good signal. This pin is used to detect the VDIMM (2.5V/1.8V) power or power-good signal. 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. Active high. This signal indicates that the system is in S3 state. Active-High of this signal indicates all of the voltage from the ATX power supply is valid. Ground 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. 2 3 4 VLDT_SEN VDDA_SEN VDIMM_SEN INa INa INa 5 SB_PSON# INt 6 7 8 ACPI_S3 ATX_PWRGD GND INt INt 9 ATX_PSON# OD70 10 RST_BTN# INt 11 CPU_PWRGD OD70 4 Rev.A.03 AME ATPA02 n Pin Description (Contd.)
