CPU_STOP# Timing Diagram
CPU_STOP# is an asychronous input to the clock synthesizer. It is used to turn off the CPU clocks for low power
operation. CPU_STOP# is synchronized by the
ICS94215
. The minimum that the CPU clock is enabled (CPU_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.
CPU clock on latency is less than 4 CPU clocks and CPU clock off latency is less than 4 CPU clocks.
Notes:
1. All timing is referenced to the internal CPU clock.
2. CPU_STOP# is an asynchronous input and metastable conditions may exist. This signal is
synchronized to the CPU clocks inside the ICS94215.
3. All other clocks continue to run undisturbed.
