SDRAM clock outputs. Fanout buffer outputs from

BUFFER IN pin.(Controlled by chipset) They are

disabled when PD# is set LOW.

Free running PCI clock during normal operation.

Latched Input. Mode=1, Pin 2 is REF0; Mode=0,

Pin2 is CPU_STOP#

Low skew (< 250ps) PCI clock outputs.

Latched input for FS1 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 1-48ns skew(CPU early).

Inputs to fanout for SDRAM outputs.

The all clocks will be stopped when this pin set to

LOW .
