• Lock option for the configuration and data of each output pin
• 15 GPIO ports generate IRQ/SMI/SIOPME# for wake-up events; each GPIO has
separate:
• Enable control of event status routing to IRQ
• Enable control of event status routing to SMI
• Enable control of event status routing to SIOPME# (via SWC)
• Polarity and edge/level selection
• Programmable de-bouncing
3.3.4.4 Power Management
•
Supports ACPI Specification Revision 2.0b, July 27, 2000
• System Wake-Up Control (SWC)
• Optional routing of events to generate SCI (SIOPME#) on detection of:
• Keyboard or Mouse events
• Ring Indication RI on each of the two serial ports
• General-Purpose Input Events from 15 GPIO pins
• IRQs of the Keyboard and Mouse Controller
• IRQs of the other internal modules
• Optional routing of the SCI (SIO PME#) to generate IRQ (SERIRQ)
• Implements the GPE1_BLK of the ACPI General Purpose (Generic)
Register blocks with child” events
• VSB3-powered event detection and event-logic configuration
