Processor Power Status Indicator (PSI#) Signal
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.
