ADC Characteristics
1. Corresponds to 13 clock cycles: 3 clock cycles for track and hold acquisition time and 10 clock cycles for conversion.
2. Corresponds to 15 clock cycles: 5 clock cycles for track and hold acquisition time and 10 clock cycles for conversion.
1. ADVREF should be connected to GND to avoid extra consumption in case ADC is not used.
