/**
 * @addtogroup LEDTS
 * @brief LED and Touch-Sense control(LEDTS) driver for the XMC controller family.
 *
 * The LED and Touch-Sense (LEDTS) drives LEDs and controls touch pads used as human-machine interface (HMI) in an
 * application. The LEDTS can measure the capacitance of up to 8 touch pads, can also drive up to 64 LEDs in an LED matrix.
 * Touch pads and LEDs can share pins to minimize the number of pins needed for such applications, this is realized by
 * the module controlling the touch pads and driving the LEDs in a time-division multiplexed manner.
 *
 * This device contains LEDTS kernel that has an LED driving function and a touch-sensing function.
 *
 * It is recommended to set up all configurations for the LEDTS in all Special Function Registers(SFR) before
 * enabling and starting LED and/or touch-sense function(s).
 *
 * This Low Level Driver(LLD) provides APIs to configure and control LED functionality, Touch-Sense functionality and
 * features common to both functionalities.
 *
 * LED features:
 * -# Configuration structure to configure LED functionality (XMC_LEDTS_LED_CONFIG_t) and initialization funtion
 *    (XMC_LEDTS_InitLED()).
 * -# Selection of number of LED columns, active column level and enabling LED funtionality (XMC_LEDTS_InitLED()).
 * -# Setting line pattern to be displayed on LED column (XMC_LEDTS_SetLEDLinePattern()).
 * -# Brightness control of LED column (XMC_LEDTS_SetColumnBrightness()).
 * -# Setting number of columns to be activated (XMC_LEDTS_SetNumOfLEDColumns()).
 *
 * Touch-Sense features:
 * -# Configuration structure to perform basic Touch-Sense functionality (XMC_LEDTS_TS_CONFIG_BASIC_t) settings and
 *    initialization funtion (XMC_LEDTS_InitTSBasic()).
 * -# Configuration structure to perform advanced Touch-Sense functionality (XMC_LEDTS_TS_CONFIG_ADVANCED_t) settings
 *    and initialization function (XMC_LEDTS_InitTSAdvanced()).
 * -# Setting number of touch inputs and acculumate count on touch input (XMC_LEDTS_InitTSBasic()).
 * -# Enabling/disabling of common compare, Touch-Sense counter auto reset and Touch-Sense funtionality.
 *    (XMC_LEDTS_InitTSBasic()).
 * -# Set number of mask bits for time frame validation and first touch input to be active. (XMC_LEDTS_InitTSAdvanced()).
 * -# Enable/disable time frame interrupt, external pull-up on touch pin and hardware or software control of
 *    pad turn (XMC_LEDTS_InitTSAdvanced()).
 * -# Setting size of common oscillation window for all touch-sense inputs (XMC_LEDTS_SetCommonOscillationWindow()).
 * -# Setting size of oscillation window for a touch-sense input (XMC_LEDTS_SetOscillationWindow()).
 *
 * Common features:
 * -# Global configuration structure XMC_LEDTS_GLOBAL_CONFIG_t and initialization function XMC_LEDTS_InitGlobal().
 * -# Selection of Clock source for LEDTS module (XMC_LEDTS_InitGlobal()).
 * -# Kick-start and stop of LEDTS module (XMC_LEDTS_StartCounter() / XMC_LEDTS_StopCounter()).
 * -# Read and clear of interrupt status flags (XMC_LEDTS_ReadInterruptFlag() / XMC_LEDTS_ClearInterruptFlag()).
 * -# Reading of previous active column number (XMC_LEDTS_ReadFNCOL()).
 * -# Enable/Disable Interrupts(XMC_LEDTS_EnableInterrupt() / XMC_LEDTS_DisableInterrupt()).
