**`CIRQUE_PINNACLE_ATTENUATION`** is a measure of how much data is suppressed in regards to sensitivity. The higher the attenuation, the less sensitive the touchpad will be.
Default attenuation is set to 4X, although if you are using a thicker overlay (such as the curved overlay) you will want a lower attenuation such as 2X. The possible values are:
* `ADC_ATTENUATE_4X`: Least sensitive
* `ADC_ATTENUATE_3X`
* `ADC_ATTENUATE_2X`
* `ADC_ATTENUATE_1X`: Most sensitive
