The PSI# signal is asserted when the processor is in a reduced power consumption 

state. PSI# can be used to improve light load efficiency of the voltage regulator, 

resulting in platform power savings and extended battery life. The algorithm that the 

processor uses for determining when to assert PSI# is different from the algorithm 

used in previous processors.
