Figure 45 Raw acquisition mode API Flow diagramLibrary Configuration parameters for UC3LThe QTouch Library for UC3L provides a single configuration header file touch_config_at32uc3l.hfile for setting the various configuration parameters for each method. The different configurationparameters corresponding to QMatrix, QTouch Group A/B and Autononmous QTouch sensorsare listed in the Table below.ParameterSensorConfigurationPinConfigurationQMatrixQM_NUM_X_LINESQM_NUM_Y_LINESQM_NUM_SENSORSQM_NUM_ROTORS_SLIDERSQM_X_PINS_SELECTEDQM_Y_PAIRS_SELECTEDQM_SMP_DIS_PIN_OPTIONQM_VDIV_PIN_OPTIONQTouch Group A/BQTx_NUM_SENSORSQTx_NUM_ROTORS_SLIDERSQTx_SP_SELECTEDNoneAutonomousQTouchAT_SP_SELECTEDClock andRegisterConfigurationQM_GCLK_CAT_DIVQM_CAT_CLK_DIVQM_CHLENQM_SELENQM_CXDILENQM_DILENQM_DISHIFTQM_MAX_ACQ_COUNTQM_CONSENQM_INTREFSELQM_INTVREFSELQM_ENABLE_SPREAD_SPECTRUMQM_ENABLE_EXTERNAL_SYNCQM_SYNC_TIMQTx_CAT_CLK_DIVQTx_CHLENQTx_SELENQTx_DILENQTx_DISHIFTQTx_MAX_ACQ_COUNTQTx_ENABLE_SPREAD_SPECTRUMQTx_ENABLE_EXTERNAL_SYNCAT_CAT_CLK_DIVAT_CHLENAT_SELENAT_DILENAT_DISHIFTAT_MAX_ACQ_COUNTAT_ENABLE_SPREAD_ SPECTRUMAT_ENABLE_EXTERNAL_SYNCAT_FILTERAT_OUTSENSAT_SENSEAT_PTHR1348207K-AT42-09/11
