5.11.1 Features
• ACPI Power and Thermal Management Support
— Processor THRMTRIP# emergency shutdown
— ACPI 24-Bit Timer
— Software initiated throttling of processor performance for Thermal and Power Reduction
— Hardware Override to throttle processor performance when system too hot
— SCI and SMI# Generation
• PME# Signal for Wake Up from Low-Power states (PME signal shared between both
PCI and PCI-X interfaces)
