K8 Timing Controller
nGeneral Description
nFeatures
The ATPA02G is a power sequence controller for AMD
K8 processor. This part can mainly control the power
supply relationships during power up, power down, entry
and exit of any power management state in order to avoid
damage to the device and ensure proper operation of the
device.

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.
