3.9 Frequency Hopping with Autotune

This very effective noise avoidance feature is, by default, enabled.

Frequency Hopping with Autotune helps to ensure robust touch sensing under various electrical noise conditions. The noise on touch measurement data increases rapidly if the touch measurement frequency matches the frequency of the noise source. Predicting the noise frequency in varying conditions of product usage at the end customer is challenging. Frequency Hopping with Autotune enables touch to remain flexible and active to avoid noise after your product is shipped. Frequency Hopping with Autotune varies the touch measurement frequency. The built-in advanced algorithms continuously monitor incoming noise and dynamically adjust the touch measurement frequency. In short: The system actively avoids noise.
