/**
 * @addtogroup USIC
 * @brief Universal Serial Interface Channel(USIC) driver for serial communication.
 *
 * The Universal Serial Interface Channel(USIC) module is a flexible interface module
 * covering several serial communication protocols. A USIC module contains two
 * independent communication channels named USICx_CH0 and USICx_CH1, with x
 * being the number of the USIC module. The user can program, during run-time, which protocol will be handled
 * by each communication channel and which pins are used.
 * The driver provides APIs, configuration structures and enumerations to configure common features of multiple serial
 * communication protocols.
 * 
 * USIC driver features:
 * -# Allows configuration of FIFO for transmit and receive functions.
 * -# Provides a structure type XMC_USIC_CH_t to represent the USIC channel registers in a programmer
 friendly format.
 * -# Allows configuration of automatic update for frame length, word length, slave select or slave address.
 * -# Allows transmission of data to FIFO using XMC_USIC_CH_TXFIFO_PutData() and XMC_USIC_CH_TXFIFO_PutDataFLEMode()
 * -# Allows reading of received data in FIFO using XMC_USIC_CH_RXFIFO_GetData()
 * -# Allows configuration of baudrate using XMC_USIC_CH_SetBaudrate()
 * -# Provides API to trigger interrupts using XMC_USIC_CH_TriggerServiceRequest()
