For synchronous Chipset, CPU_STOP# pin is a synchronous
active low
input pin used to stop the
CPU clocks for low power operation. This pin is asserted synchronously by the external control logic
at the rising edge of free running PCI clock(PCICLK_F). All other clocks will continue to run while
the CPU clocks are stopped. The CPU clocks will always be stopped in a low state and resume
output with full pulse width. In this case, CPU
c
locks on latency
is less than 2 CPU clocks and
c
locks off latency
is less then 2 CPU clocks.
