/**
 * @addtogroup UART
 * @brief Universal Asynchronous Receiver/Transmitter (UART) driver for XMC microcontroller family.
 *
 * The UART driver uses Universal Serial Interface Channel(USIC) module to implement UART protocol.
 * It provides APIs to configure USIC channel for UART communication. The driver enables the user
 * in getting the status of UART protocol events, configuring interrupt service requests, protocol
 * related parameter configuration etc.
 * 
 * UART driver features:
 * -# Configuration structure XMC_UART_CH_CONFIG_t and initialization function XMC_UART_CH_Init()
 * -# Enumeration of events with their bit masks @ref XMC_UART_CH_EVENT_t, @ref XMC_UART_CH_STATUS_FLAG_t
 * -# Allows the selection of input source for the DX0 input stage using the API XMC_UART_CH_SetInputSource()
 * -# Allows configuration of baudrate using XMC_UART_CH_SetBaudrate() and configuration of data length using 
 XMC_UART_CH_SetWordLength() and XMC_UART_CH_SetFrameLength()
 * -# Provides the status of UART protocol events, XMC_UART_CH_GetStatusFlag()
 * -# Allows transmission of data using XMC_UART_CH_Transmit() and gets received data using XMC_UART_CH_GetReceivedData()
 *
