Processor Power Status Indicator (PSI#) Signal
The Intel Pentium M processor incorporates the PSI# signal that is asserted when the processor is
in a low power (Deep Sleep or Deeper Sleep) state. This signal is asserted upon Deep Sleep entry
and deasserted upon exit. PSI# can be used to improve the light load efficiency of the voltage
regulator, resulting in platform power savings and extended battery life. PSI# can also be used to
simplify voltage regulator designs since it removes the need for integrated 100 s timers required
to mask the PWRGOOD signal during Deeper Sleep transitions. It also reduces PWRGOOD
monitoring requirements in the Deeper Sleep state.
