+**`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_2X`
+* `ADC_ATTENUATE_1X`: Most sensitive
