6.3.10 Raw acquisition mode support for UC3L
The QTouch Library Raw acquisition mode can be used with QMatrix, QTouch Group A and
QTouch Group B methods. When raw data acquisition mode is used, once the raw acquisition
data is available from the CAT module for all the sensors, the measure_complete_callback
function is immediately called with acquisition data (channel_signals). The channel_references,
sensor_states and rotor_slider_values data are not updated by the Touch Library in this mode.
