Suspend Type
S1 (POS) Power On suspend
All devices are powered up except for the clock synthesizer. The Host and
PCI clocks are inactive and PIIX4 provides control signals and 32-kHz Suspend
Clock (SUSCLK) to allow for DRAM refresh and to turn off the clock synthe-
sizer. The only power consumed in the system is due to DRAM Refresh and
leakage current of the powered devices. When the system resumes from
POS, PIIX4 can optionally resume without resetting the system, can reset the
processor only, or can reset the entire system. When no reset is performed,
PIIX4 only needs to wait for the clock synthesizer and processor PLLs to lock
before the system is resumed. This takes typically 20 ms.
S3 (STR) Suspend To RAM
Power is removed from most of the system components during STR, except
the DRAM. Power is supplied to Suspend Refresh logic in the Host Controller,
and RTC and Suspend Well logic in PIIX4. PIIX4 provides control signals and
32-kHz Suspend Clock (SUSCLK) to allow for DRAM refresh and to turn off
the clock synthesizer and other power planes.
Modem Use IRQ
Name the interrupt request (IRQ) assigned to the modem (if any) on your
system. Activity of the selected IRQ always awakens the system.
Suspend Mode
When the suspend mode has been enabled after the selected period of
system inactivity, all devices except CPU will be shut down.
