... CLK_STOP asychronous input to the clock synthesizer used to turn off the CPU clocks for low power operation. CLK_STOP# is synchronized by the ICS9248-195. The minimum that the CPU clock is enabled (CLK_STOP# high pulse) is 100 CPU clocks. All other clocks will continue to run while the CPU clocks are disabled. The CPU clocks will always be stopped in a low state and start in such a manner that guarantees the high pulse width is a full pulse ...
