/** @addtogroup uart_defines
 *
 * @brief UART registers are mostly equivalent to USART registers.
 *
 * USART and UART registers are equivalent except [in UART registers]:
 *
 *  * USART_CTRL: SYNC, CSMA, SMSDELAY, SSSEARLY, CSINV, CPOL and CPHA
 *      (Synchronous operation not available)
 *  * USART_STATUS: MASTEREN (Synchronous operation not available)
 *  * USART_CTRL: MSBF (transmission LSB first only)
 *  * USART_CTRL: AUTOCS (chip-select not available)
 *  * USART_CTRL: SCMODE (SmartCard mode not available)
 *  * USART_FRAME: DATABITS (limited framesize. 8-9 databits only)
 *  * USART_IRCTRL: IREN (IrDA not available)
 *   (except DATABITS, all the above are 0)
 *
 * full text: (p495, "d0183_Rev1.10" EFM32LG-RM)
 *  - "18.3 Functional Description",
 *  - "18.4 Register Description"
 *  - "18.5 Register Map"
 *
 * use USART macro's to manipulate UART registers.
