  The sensing pads can be arranged in different combinations (e.g., matrix, slider), so that a larger area or more points can be detected. The touch pad sensing process is under the control of a hardware-implemented finite-state machine (FSM) which is initiated by software or a dedicated hardware timer.
 
-Design, operation, and control registers of a touch sensor are discussed in `{IDF_TARGET_NAME} Technical Reference Manual <IDF_TARGET_TRM_URL>`_ (PDF). Please refer to this manual for additional details on how this subsystem works.
