Basic mode disables all additional computation features. This mode closely resembles a typical ADC module (without computation), and is considered the Legacy mode. Threshold comparison tests are still performed, which may or may not set the ADTIF flag, and the Double Sampling mode, Continuous mode, and all CVD features are still available. No accumulation occurs, and no features involving the digital filter or average features are used. The auto-conversion trigger feature is still available in Basic mode.
