Hello, I'm trying use ADC at FRDM-K22F, it's working, but I didn't get success on calculate the ADC clock. I'm using for calculate the ADC clock, but the result the calculator don't is equal at result of conversion.


I'm setting my ADC clock this way:


    adcUserConfig.resolution = kAdc16ResolutionBitOf16;

    adcUserConfig.highSpeedEnable = false;  

    adcUserConfig.clkSrc = kAdc16ClkSrcOfBusClk;

    adcUserConfig.lowPowerEnable = false;

    adcUserConfig.asyncClkEnable = false;

    adcUserConfig.longSampleTimeEnable = false;

    adcUserConfig.longSampleCycleMode = kAdc16LongSampleCycleOf24;

    adcUserConfig.clkDividerMode = kAdc16ClkDividerOf8;  


    ADC16_DRV_Init(ADC16_INSTANCE, &adcUserConfig);



What's the result of ADC clock for this example?
