remains on during S0-S1 states, and may be shut
off during S3-S5. The PCI clock to peripherals
may be shut off using the CLKRUN# protocols.

External Super I/O. Shut off in S3 or below.
USB 2.0 logic close to the pins. Shut off when the
48 MHz clock input is shut off (S1 for low power,
as well as S3 or below)
Used by ACPI timer. Also used by the Multimedia
Timers Logic. Shut off in S1 for low power, as well
as S3 or below.
AC’97 Link. Generated by AC’97 CODEC. May be
shut off by codec in D3, as well as S1 for low
power, and S3 or below.
RTC, Power Management. The Intel
ICH has its own oscillator.
Always running, even in G3 state.

clock output. The Intel
UART clock must use a 14.7456 MHz
frequency; most clock chips do not
provide this frequency. An option will be to
use the 48.0 MHz clock.
