AD_CK clock is always half of the ADC module input clock defined via the auxiliary clock divider for the ADC.
When configured to allow 60 MHz ADC, the minimum ADC clock speed is 9 MHz, below which precision is lost.
This parameter does not include the sample time t
time to load the result register with the conversion result.
20 MHz ADC clock. Specific prescaler is programmed on MC_PLL_CLK to provide 20 MHz clock to the ADC.
