Power Management Features:
Note:
1. LOW means outputs held static LOW as per latency requirement next page.
2. On means active.
3. PD# pulled Low, impacts all outputs including REF and 48 MHz outputs.
4.All 3V66 as well as all CPLU clocks should stop cleanly when CPU_STOP# is pulled LOW.
5. CPU/2, IOAPIC, REF, 48 MHz signals are not controlled by the CPU_STOP# functionality and are enabled all in all conditions
except PD# = LOW
