SDRAM_STOP# Timing Diagram
SDRAM_STOP# is an asychronous input to the clock synthesizer. It is used to stop SDRAM clocks for low power
operation. SDRAM_STOP# is synchronized to complete it's current cycle, by the ICS94209. All other clocks will
continue to run while the SDRAM clocks are disabled. The SDRAM 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.
Notes:
1. All timing is referenced to the internal CPU clock.
2. SDRAM is an asynchronous input and metastable conditions may exist. This signal is
synchronized to the SDRAM clocks inside the ICS94209.
3. All other clocks continue to run undisturbed.
