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 I/F. These only go to external PCI and
LPC devices. Will stop based on CLKRUN# (and
STP_PCI#) in mobile configurations.
Super I/O, USB controllers. 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. Expected
to be shut off during S3 or below in desktop
configurations or S1 or below in mobile configurations.
AC-link. Generated by AC ’97 Codec. Can be shut by
codec in D3. Expected to be shut off during S3 or below
in desktop configurations or S1 or below in mobile
configurations.
NOTE: For use only in AC ‘97 mode.
Generated by the LAN Connect component. Expected
to be shut off during S3 or below in desktop
configurations or S1 or below in mobile configurations.
