Power-Up Control
The module’s SUS_S3# signal controls the ATX power supply control signal (PS_ON#). When the system goes to Suspend to RAM (S3) or
Soft Off (S5), the module’s chipset asserts the ‘SUS_S3#’ signal. Through the use of an inverter, the low active ‘PS_ON#’ signal goes high and
switches off the ATX power supply.
When the system is in a power-down system state, any system wake-up event invokes the chipset of the module to deassert the ‘SUS_S3#’
signal. With the deassertion, the system transitions to Full-On state (S0).

Module Type Detection
The signals TYPE0#, TYPE1#, TYPE2# and TYPE10# indicate the pinout type of the module connected to the carrier board. These pins are either
open (N.C), strapped to ground (GND) or connected to 12 V by the module as shown in the table below.
