When operating ML22Q53x, ML22Q62x, and ML22Q66x with an external clock, if the external clock stops, will the speech synthesis LSI also stop?
- These series are equipped with clock backup function. When the external clock stops, the clock backup function is activated and automatically switches to the built-in RC oscillator circuit (4.096MHz). At this time, the speech synthesis LSI does not stop because it operates with built-in RC oscillation.
