* @note For any given channel, this function must be called before the first time conversion.

* The default ADC full-scale voltage is 1.1V. To read higher voltages (up to the pin maximum voltage,
|
|
* usually 3.3V) requires setting >0dB signal attenuation for that ADC channel.
|

* - 0dB attenuaton (ADC_ATTEN_DB_0) gives full-scale voltage 1.1V
|

* - 2.5dB attenuation (ADC_ATTEN_DB_2_5) gives full-scale voltage 1.5V
|
|
* - 6dB attenuation (ADC_ATTEN_DB_6) gives full-scale voltage 2.2V

|
* @note At 11dB attenuation the maximum voltage is limited by VDD_A, not the full scale voltage.

*

* Due to ADC characteristics, most accurate results are obtained within the following approximate voltage ranges:
|
|
*
|
|
* - 0dB attenuaton (ADC_ATTEN_DB_0) between 100 and 950mV
|

|
|
* - 11dB attenuation (ADC_ATTEN_DB_11) between 150 to 2450mV
