Based on the input parameters, the CAT module is initialized with QMatrix method Pin
and Register configuration.
The Analog comparators necessary for QMatrix operation are initialized by this API.
Both p_qm_config & p_general_config members of the input configuration structure must
point to valid configuration data.
The General configuration data provided by the p_general_config pointer is common to
both QMatrix, QTouch Group A, QTouch Group B and Autonomous Touch sensors.
touch_ret_t touch_qm_sensor_config(
This API configures a single QMatrix Key, Rotor or Slider.
The user must provide all the sensor specific settings as input to this API.
Rotor / Slider sensor will occupy contiguous channels from from_channel to to_channel.
For QMatrix acquisition method, 3 to 8 Touch channels per rotor / slider are supported.
Keys are always formed using 1 Touch channel.
