For offset calibration purpose the offset of the certain differential channels can be measure by
selecting the same input for both negative and positive input. This calibration can be done for
ADC0, ADC3 and ADC7.
level.
• Bit 7 – ADEN: ADC Enable
Writing this bit to one enables the ADC. By writing it to zero, the ADC is turned off. Turning the
ADC off while a conversion is in progress, will terminate this conversion.
