CNY7: Power Up Config
Jumper
*The Super I/O detects a power button event using the 'PSIN' pin. When a power button event occurs, the power-
up logic of the Super I/O sets 'PSOUT#' low and asserts 'PWRBTN#' of the module's chipset. The Super I/O also
sets the 'PWRCTL#' pin to low, which asserts the 'PS_ON#' signal and switches on the ATX power supply.
