Functional Description

PROCPWRGD out to the processor indicates that the primary power is ramped up and stable. PROCPWRGD will be undriven by the PCH (high Z) when RSMRST# is asserted and driven high after RSMRST# is de-asserted.

If THRMTRIP# goes active, the processor is indicating an overheat condition, and the PCH will immediately transition to an S5 state. CPU_​GP can be used from external sensors for the thermal management.
