+ * \defgroup asfdoc_sam0_sercom_usart_group SAM Serial USART (SERCOM USART) Driver
+ *
+ * This driver for Atmel® | SMART ARM®-based microcontrollers provides
+ * an interface for the configuration and management of the SERCOM module in
+ * its USART mode to transfer or receive USART data frames. The following driver
+ * API modes are covered by this manual:
+ *
+ * - Polled APIs
+ * \if USART_CALLBACK_MODE
+ * - Callback APIs
+ * \endif
+ *
+ * The following peripheral is used by this module:
+ * - SERCOM (Serial Communication Interface)
+ *
+ * The following devices can use this module:
+ * - Atmel | SMART SAM D20/D21
+ * - Atmel | SMART SAM R21
+ * - Atmel | SMART SAM D09/D10/D11
+ * - Atmel | SMART SAM D10/D11

+ * - Atmel | SMART SAM HA1

+ *
+ * \section asfdoc_sam0_sercom_usart_prerequisites Prerequisites
+ *
+ * To use the USART you need to have a GCLK generator enabled and running
+ * that can be used as the SERCOM clock source. This can either be configured
+ * in conf_clocks.h or by using the system clock driver.
+ *
+ * \section asfdoc_sam0_sercom_usart_overview Module Overview
+ *
+ * This driver will use one (or more) SERCOM interface(s) in the system
+ * and configure it to run as a USART interface in either synchronous
+ * or asynchronous mode.

+ * \subsection asfdoc_sam0_sercom_usart_overview_sync Synchronous Mode
+ *
+ * In synchronous mode a dedicated clock line is provided; either by the USART
+ * itself if in master mode, or by an external master if in slave mode.
+ * Maximum transmission speed is the same as the GCLK clocking the USART
+ * peripheral when in slave mode, and the GCLK divided by two if in
+ * master mode. In synchronous mode the interface needs three lines to
+ * communicate:
+ * - TX (Transmit pin)
+ * - RX (Receive pin)
+ * - XCK (Clock pin)
+ *
+ * \subsubsection asfdoc_sam0_sercom_usart_overview_sync_sampling Data Sampling
+ * In synchronous mode the data is sampled on either the rising or falling edge
+ * of the clock signal. This is configured by setting the clock polarity in the
+ * configuration struct.
+ *
+ * \subsection asfdoc_sam0_sercom_usart_overview_async Asynchronous Mode
+ *
+ * In asynchronous mode no dedicated clock line is used, and the communication
+ * is based on matching the clock speed on the transmitter and receiver. The
+ * clock is generated from the internal SERCOM baudrate generator, and the
+ * frames are synchronized by using the frame start bits. Maximum transmission
+ * speed is limited to the SERCOM GCLK divided by 16.
+ * In asynchronous mode the interface only needs two lines to communicate:
+ * - TX (Transmit pin)
+ * - RX (Receive pin)
+ *
+ * \subsubsection asfdoc_sam0_sercom_usart_overview_async_clock_matching Transmitter/receiver Clock Matching
+ *
+ * For successful transmit and receive using the asynchronous mode the receiver
+ * and transmitter clocks needs to be closely matched. When receiving a frame
+ * that does not match the selected baudrate closely enough the receiver will
+ * be unable to synchronize the frame(s), and garbage transmissions will
+ * result.
+ *
+ * \subsection asfdoc_sam0_sercom_usart_parity Parity
+ * Parity can be enabled to detect if a transmission was in error. This is done
+ * by counting the number of "1" bits in the frame. When using even parity the
+ * parity bit will be set if the total number of "1"s in the frame are an even
+ * number. If using odd parity the parity bit will be set if the total number
+ * of "1"s are odd.
+ *
+ * When receiving a character the receiver will count the number of "1"s in the
+ * frame and give an error if the received frame and parity bit disagree.
+ *
+ * \subsection asfdoc_sam0_sercom_usart_overview_pin_configuration GPIO Configuration
+ *
+ * The SERCOM module has four internal pads; the RX pin can be placed freely on
+ * any one of the four pads, and the TX and XCK pins have two predefined
+ * positions that can be selected as a pair. The pads can then be routed to an
+ * external GPIO pin using the normal pin multiplexing scheme on the SAM.
+ *
+ * \section asfdoc_sam0_sercom_usart_special_considerations Special Considerations
+ *
+ * \if USART_CALLBACK_MODE
+ * Never execute large portions of code in the callbacks. These
+ * are run from the interrupt routine, and thus having long callbacks will
+ * keep the processor in the interrupt handler for an equally long time.
+ * A common way to handle this is to use global flags signaling the
+ * main application that an interrupt event has happened, and only do the
+ * minimal needed processing in the callback.
+ * \else
+ * No special considerations.
