8            Some ESP32s have Two Point calibration values burned into eFuse BLOCK3.
9            This option will allow the ADC calibration component to characterize the
10            ADC-Voltage curve using Two Point values if they are available.

17            Some ESP32s have Vref burned into eFuse BLOCK0. This option will allow
18            the ADC calibration component to characterize the ADC-Voltage curve using
19            eFuse Vref if it is available.

25        help
26            This option will allow the ADC calibration component to use Lookup Tables
27            to correct for non-linear behavior in 11db attenuation. Other attenuations
28            do not exhibit non-linear behavior hence will not be affected by this option.
