Low-Power States and PROCHOT# Behavior

Depending on package power levels during package C-states, outbound PROCHOT# may de-assert while the processor is idle as power is removed from the signal. Upon wake up, if the processor is still hot, the PROCHOT# will re-assert, although typically package idle state residency should resolve any thermal issues. The PECI interface is fully operational during all C-states and it is expected that the platform continues to manage processor IA core and package thermals even during idle states by regularly polling for thermal data over PECI.
