3.8.5 Frequency Hopping with Auto-Tune

The MTCH1030 touch controller provides robust touch sensing under electrical noise. Active noise avoidance technologies, such as frequency hopping with auto-tune, are embedded. As a result, the MTCH1030 proactively adapts the touch sensing frequency according to the noise scenario during run-time. No host intervention is needed.
