hello ,
Datasheet says external clock frequency range is 25-52MHz when CLK DIV is 1.
Could you tell me what happens when external clock is less than 24MHz? Does the device switch the oscillator from external to internal AON?
I am asking because when radiated emission test is performed, the noise peak was seen when using external clock 25MHz.
however AON does not show any noise peak.
also 24MHz external clock also showed noise peak. i want to check if device works with external clock at 24MHz, or device uses AON if extenal clock is low like 24MHz.
