FUNCTION
CPUCLK_F
Free running CPU clock. Not affected by
CPU_STOP#
Low skew (< 250ps) clock outputs for host
frequencies such as CPU, Chipset and Cache.
Powered by VddL2. Low if CPU_STOP# is low.
This asynchronous input halts CPUCLK[0:2] and
SDRAM(0:11) at logic level when driven low.
Free running SDRAM clock. Not affected by
CPU_STOP#
SDRAM clock outputs. Fanout buffer outputs from
BUFFER IN pin.(Controlled by chipset)

*MODE
I/O
Free running PCI clock during normal operation.
Latched Input. Mode=1, Pin 2 is REF0; Mode=0,
Pin2 is PCI_STOP#
Low skew (< 250ps) PCI clock outputs.
Latched input for FS3 at initial power up for H/W
selecting the output frequency of CPU, SDRAM and
PCI clocks.
Low skew (< 250ps) PCI clock outputs. Synchronous
to CPU clocks with 1/-4ns skew(CPU early).
