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 .
