Free-running PCI Clock to Intel
clock remains on during S0 and S1 (in desktop)
state, and is expected to be shut off during S3
or below in desktop configurations or S1 or
below in mobile configurations.
PCI Bus, LPC Interface. These clocks only go to
external PCI and LPC devices. These clocks will
stop based on CLKRUN# (and STP_PCI#) in
mobile configurations.
Super I/O, USB controllers. This clock is
expected to be shut off during S3 or below in
desktop configurations or S1 or below in mobile
configurations.
Used for ACPI timer and Multimedia Timers.
This clock is expected to be shut off during S3
or below in desktop configurations or S1 or
