System Wake-Up Control (SWC)
3.1
OVERVIEW
The SWC recognizes the following maskable system events:
q
Modem ring (RI1 and RI2 pins)
q
Telephone ring (RING input pin)
q
Keyboard activity or specific programmable key sequence
q
Mouse activity or specific programmable sequence of clicks and movements
q
Programmable Consumer Electronics IR (CEIR) address
q
Wake-up on module IRQs for FDC, Parallel Port, Serial Ports 1 and 2, Mouse, KBC, ACB, Fan Speed Control and
Monitor (FSCM) and WATCHDOG Timer (WDT), Game Port and MIDI Port
q
Eight VSB-powered, general-purpose input events (via GPIOE0-5 and GPIE6-7)
q
15 VDD-powered, GPIO-triggered events (via GPIO00-07, GPIO10-14, GPIO16-17)
q
Software event.
The SWC notifies the device when any of these events occur by asserting one or more of the following output pins:
q
Power-Up Request (PWUREQ)
q
System Management Interrupt (SMI)
q
Interrupt Request (via SERIRQ)
q
Power Button (PWBTOUT)
