Clock Generators
The clock generator is expected to provide the frequencies shown in
Clock Control Signals from ICH4 to Clock Synthesizer
The clock generator is assumed to have direct connect from the following ICH4 signals:
AC_BIT_CLK

CLK14
Clock
STP_CPU#: Stops processor clocks in C3 state
STP_PCI#: Stops system PCI clocks (not the ICH4 free-running 33 MHz clock) due to
CLKRUN# protocol
SLP_S1#: Stops all clocks in S1-M

Should be running in all Cx states. Stopped in S1-M based on
SLP_S1# assertion. Stopped in S3 ~ S5 based on SLP_S3#
assertion.
Free-running (not affected by STP_PCI# PCI Clock to ICH4.
This is not the system PCI clock. This clock must keep running
in S0 while the system PCI clock may stop based on CLKRUN#
protocol. This clock is stopped in S1-M based on SLP_S1#
assertion. Stopped in S3 ~ S5 based on SLP_S3# assertion.
Used by USB Controllers. This clock is stopped in S1-M based
on SLP_S1# assertion. Stopped in S3 ~ S5 based on SLP_S3#
assertion.
Used by ACPI timers. This clock is stopped in S1-M based on
SLP_S1# assertion. Stopped in S3 ~ S5 based on SLP_S3#
assertion.
AC ’97 Link. Control policy is determined by the clock source.
Used for ICH4-processor interrupt messages. Should be
running in C0, C1 and C2. Stopped in C3 based on STP_CPU#
assertion. Stopped in S1-M based on SLP_S1# assertion.
Stopped in S3 ~ S5 based on SLP_S3# assertion.
LAN Connect link. Control policy is determined by the clock
source.
