3.7.3 ADC Input Clock Register
This register selects the clock frequency for the ADC.
ADIV2–ADIV0 — ADC Clock Prescaler Bits
Freescale Semiconductor
ADIV2, ADIV1, and ADIV0 form a 3-bit field which selects the divide ratio used by the ADC to generate
the internal ADC clock.
set according to the MCU operating voltage. Lower operating voltages will require lower ADC clock
frequencies for best accuracy. The analog input level should remain stable for the entire conversion
time (maximum = 17 ADC clock cycles).
