Analog-to-Digital Converter (ADC)
9.7.2 ADC Data Register
One 8-bit result register is provided. This register is updated each time an ADC conversion completes.
9.7.3 ADC Input Clock Register
This register selects the clock frequency for the ADC
ADIV[2:0] — ADC Clock Prescaler Bits
102
ADIV[2:0] form a 3-bit field which selects the divide ratio used by the ADC to generate the internal ADC
clock.
