-/**
- * \page asfdoc_sam0_sercom_i2c_slave_dma_use_case Quick Start Guide for Using DMA with SERCOM I2C Slave
- *
- * The supported board list:
- *    - SAMD21 Xplained Pro
- *    - SAMR21 Xplained Pro
- *    - SAML21 Xplained Pro
- *
- * In this use case, the I<SUP>2</SUP>C will used and set up as follows:
- *  - Slave mode
- *  - 100KHz operation speed
- *  - Not operational in standby
- *  - 65535 unknown bus state timeout value
- *
- *
- * \section asfdoc_sam0_sercom_i2c_slave_dma_use_case_prereq Prerequisites
- * The device must be connected to an I<SUP>2</SUP>C slave.
- *
- * \section asfdoc_sam0_sercom_i2c_slave_dma_use_setup Setup
- *
- * \subsection asfdoc_sam0_sercom_i2c_slave_dma_use_setup_code Code
- * The following must be added to the user application:
- *
- * - Address to respond to:
- * \snippet qs_i2c_slave_dma.c address
- *
- * - A sample buffer to send, number of entries to send and address of slave:
- * \snippet qs_i2c_slave_dma.c packet_data
- *
- * - Globally accessible module structure:
- * \snippet qs_i2c_slave_dma.c module
- *
- * - Function for setting up the module:
- * \snippet qs_i2c_slave_dma.c initialize_i2c
- *
- * - Globally accessible DMA module structure:
- * \snippet qs_i2c_slave_dma.c dma_resource
- *
- * - Globally accessible DMA transfer descriptor:
- * \snippet qs_i2c_slave_dma.c transfer_descriptor
- *
- * - Function for setting up the DMA resource:
- * \snippet qs_i2c_slave_dma.c config_dma_resource
- *
- * - Function for setting up the DMA transfer descriptor:
- * \snippet qs_i2c_slave_dma.c setup_dma_transfer_descriptor
- *
- * - Add to user application \c main():
- * \snippet qs_i2c_slave_dma.c init
- *
- * \subsection asfdoc_sam0_sercom_i2c_slave_dma_use_setup_workflow Workflow
- * \subsubsection asfdoc_sam0_sercom_i2c_slave_dma_use_setup_workflow_i2c Configure and enable SERCOM:
- * \snippet qs_i2c_slave_dma.c initialize_i2c
- * -# Create and initialize configuration structure.
- *    \snippet qs_i2c_slave_dma.c init_conf
- * -# Change settings in the configuration.
- *    \snippet qs_i2c_slave_dma.c conf_changes
- * -# Initialize the module with the set configurations.
- *    \snippet qs_i2c_slave_dma.c init_module
- * -# Enable the module.
- *    \snippet qs_i2c_slave_dma.c enable_module
- *
- * \subsubsection asfdoc_sam0_sercom_i2c_slave_dma_use_setup_workflow_dma Configure DMA
- * -# Create a DMA resource configuration structure, which can be filled out to
- *    adjust the configuration of a single DMA transfer.
- *    \snippet qs_i2c_slave_dma.c dma_setup_1
- *
- * -# Initialize the DMA resource configuration struct with the module's
- *    default values.
- *    \snippet qs_i2c_slave_dma.c dma_setup_2
- *    \note This should always be performed before using the configuration
- *          struct to ensure that all values are initialized to known default
- *          settings.
- *
- * -# Set extra configurations for the DMA resource. It is using peripheral
- *    trigger. SERCOM RX trigger causes a beat transfer in this
- *    example.
- *    \snippet qs_i2c_slave_dma.c dma_setup_3
- *
- * -# Allocate a DMA resource with the configurations.
- *    \snippet qs_i2c_slave_dma.c dma_setup_4
- *
- * -# Create a DMA transfer descriptor configuration structure, which can be
- *    filled out to adjust the configuration of a single DMA transfer.
- *    \snippet qs_i2c_slave_dma.c dma_setup_5
- *
- * -# Initialize the DMA transfer descriptor configuration struct with the module's
- *    default values.
- *    \snippet qs_i2c_slave_dma.c dma_setup_6
- *    \note This should always be performed before using the configuration
- *          struct to ensure that all values are initialized to known default
- *          settings.
- *
- * -# Set the specific parameters for a DMA transfer with transfer size, source
- *    address, and destination address.
- *    \snippet qs_i2c_slave_dma.c dma_setup_7
- *
- * -# Create the DMA transfer descriptor.
- *    \snippet qs_i2c_slave_dma.c dma_setup_8

- * \section asfdoc_sam0_sercom_i2c_slave_dma_use_implemenation Implementation
- * \subsection asfdoc_sam0_sercom_i2c_slave_dma_use_implemenation_code Code
- * Add to user application \c main():
- * \snippet qs_i2c_slave_dma.c main
- *
- * \subsection asfdoc_sam0_sercom_i2c_slave_dma_use_implemenation_workflow Workflow
- * -# Start to wait a packet from master.
- *    \snippet qs_i2c_slave_dma.c wait_packet
- *
- * -# Once data ready, clear the address match status.
