What is the appropriate configuration to run the K65 at 120MHz without an external 16MHz oscillator?

Hi  john,

You can't configure K65 @120 MHz using 32K External Oscillator.

When using 32K external oscillator, the FLL is needed.

Calculation 120MHz = 2929 × fFLL_ref ,  then the fFLL_ref need to be equal to 40969.6Hz.

Best Regards,

Robin
