* @brief Delta Sigma Demodulator (DSD) driver for the XMC4500, XMC4400 and XMC4800 microcontroller family <br>
 *
 * The DSD unit provides a series of digital input channels accepting data streams from external modulators
 * using the Delta/Sigma (DS) conversion principle. The on-chip demodulator channels convert these inputs to 
 * discrete digital values.
 * DSD unit can be used for isolated current/voltage measurement and for sensor interfaces.<br>
 *
 * Driver is divided in six DSD functional blocks -
 * - Main Filter (APIs prefixed with XMC_DSD_CH_MainFilter),
 * - Aux Filter (APIs prefixed with XMC_DSD_CH_AuxFilter),
 * - Integrator (APIs prefixed with XMC_DSD_CH_Integrator),
 * - Timestamp  (APIs prefixed with XMC_DSD_CH_Timestamp),
 * - Rectification (APIs prefixed with XMC_DSD_CH_Rectify),
 * - Carrier Generator (APIs prefixed with XMC_DSD_Generator)
 *
 * DSD driver features:
 * -# DSD channel Configuration structure XMC_DSD_CH_CONFIG_t initialization function XMC_DSD_CH_Init() to configure all the functional blocks (except carrier generator)
 * -# Configuration structure XMC_DSD_GENERATOR_CONFIG_t and initialization function XMC_DSD_Generator_Init() to configure carrier generator
 * -# Configuration structure XMC_DSD_CH_FILTER_CONFIG_t and initialization function XMC_DSD_CH_MainFilter_Init() to configure main  filter
 * -# Configuration structure XMC_DSD_CH_AUX_FILTER_CONFIG_t and initialization function XMC_DSD_CH_AuxFilter_Init() to configure auxilary  filter
 * -# Configuration structure XMC_DSD_CH_INTEGRATOR_CONFIG_t and initialization function XMC_DSD_CH_Integrator_Init() to configure integrator
 * -# Configuration structure XMC_DSD_CH_TIMESTAMP_CONFIG_t and initialization function XMC_DSD_CH_Timestamp_Init() to configure timestamp
 * -# Configuration structure XMC_DSD_CH_RECTIFY_CONFIG_t and initialization function XMC_DSD_CH_Rectify_Init() to configure rectifier
