*
*
* \section asfdoc_sam0_dac_prerequisites Prerequisites
*
* There are no prerequisites for this module.
*
*
* \section asfdoc_sam0_dac_module_overview Module Overview
*
* The Digital-to-Analog converter converts a digital value to analog voltage.
* The SAM DAC module has one channel with 10-bit resolution,
* and is capable of converting up to 350k samples per second (ksps).
*
* A common use of DAC is to generate audio signals by connecting the DAC
* output to a speaker, or to generate a reference voltage; either for an
* external circuit or an internal peripheral such as the Analog Comparator.
*
* After being set up, the DAC will convert new digital values written to the
* conversion data register (DATA) to an analog value either on the VOUT pin of
* the device, or internally for use as an input to the AC, ADC, and other analog
* modules.
*
* Writing the DATA register will start a new conversion. It is also possible
* to trigger the conversion from the event system.
*
* A simplified block diagram of the DAC can be seen in
* \ref asfdoc_sam0_dac_module_block_diagram "the figure below".
*
* \anchor asfdoc_sam0_dac_module_block_diagram
* \image html dac_block_diagram.svg "DAC Block Diagram"
*
* \subsection asfdoc_sam0_dac_conversion_range Conversion Range
* The conversion range is between GND and the selected voltage reference.
* Available voltage references are:
* \li AVCC voltage reference
* \li Internal 1V reference (INT1V)
* \li External voltage reference (AREF)
*
* \note Internal references will be enabled by the driver, but not disabled.
* Any reference not used by the application should be disabled by the application.
*
* The output voltage from a DAC channel is given as:
* \f[
* V_{OUT} = \frac{DATA}{0x3FF} \times VREF
* \f]
*
* \subsection asfdoc_sam0_dac_conversion Conversion
* The digital value written to the conversion data register (DATA) will be
* converted to an analog value.
* Writing the DATA register will start a new conversion.
* It is also possible to write the conversion data to the DATABUF register,
* the writing of the DATA register can then be triggered from the event
* system, which will load the value from DATABUF to DATA.
*
* \subsection asfdoc_sam0_dac_analog_output Analog Output
* The analog output value can be output to either the VOUT pin or internally,
* but not both at the same time.
*
* \subsubsection asfdoc_sam0_dac_analog_output_external External Output
* The output buffer must be enabled in order to drive the DAC output to the
* VOUT pin. Due to the output buffer, the DAC has high drive strength, and is
* capable of driving both resistive and capacitive loads, as well as loads
* which combine both.
*
* \subsubsection asfdoc_sam0_dac_analog_output_internal Internal Output
* The analog value can be internally available for use as input to the
* AC or ADC modules.
*
* \subsection asfdoc_sam0_dac_events Events
* Events generation and event actions are configurable in the DAC.
* The DAC has one event line input and one event output: <i>Start Conversion</i>
* and <i>Data Buffer Empty</i>.
*
* If the Start Conversion input event is enabled in the module configuration,
* an incoming event will load data from the data buffer to the data register
* and start a new conversion. This method synchronizes conversions with
* external events (such as those from a timer module) and ensures regular and
* fixed conversion intervals.
*
* If the Data Buffer Empty output event is enabled in the module configuration,
* events will be generated when the DAC data buffer register becomes empty and
* new data can be loaded to the buffer.
*
* \note The connection of events between modules requires the use of the event
* driver to route output event of one module to the input event of another.
* For more information on event routing, refer to the documentation
* \ref asfdoc_sam0_events_group "SAM Event System (EVENTS) Driver".
*
* \subsection asfdoc_sam0_dac_data_adjust Left and Right Adjusted Values
* The 10-bit input value to the DAC is contained in a 16-bit register. This
* can be configured to be either left or right adjusted. In
* \ref asfdoc_sam0_dac_module_adj_modes "the figure below" both options are
* shown, and the position of the most (MSB) and the least (LSB) significant bits
* are indicated. The unused bits should always be written to zero.

*
* \subsection asfdoc_sam0_dac_clk_sources Clock Sources
* The clock for the DAC interface (CLK_DAC) is generated by the Power Manager.
* This clock is turned on by default, and can be enabled and disabled in the
* Power Manager.
*
* Additionally, an asynchronous clock source (GCLK_DAC) is required.
* These clocks are normally disabled by default. The selected clock source
* must be enabled in the Power Manager before it can be used by the DAC.
* The DAC core operates asynchronously from the user interface and
* peripheral bus. As a consequence, the DAC needs two clock cycles of both
* CLK_DAC and GCLK_DAC to synchronize the values written to some of the
* control and data registers.
* The oscillator source for the GCLK_DAC clock is selected in the System
* Control Interface (SCIF).
*
* \section asfdoc_sam0_dac_special_considerations Special Considerations
*
* \subsection asfdoc_sam0_dac_special_considerations_output_buffer Output Driver
* The DAC can only do conversions in Active or Idle modes. However, if the
* output buffer is enabled it will draw current even if the system is in
* sleep mode. Therefore, always make sure that the output buffer is not
* enabled when it is not needed, to ensure minimum power consumption.
*
* \subsection asfdoc_sam0_dac_special_considerations_conversion_time Conversion Time
* DAC conversion time is approximately 2.85μs. The user must ensure that new
* data is not written to the DAC before the last conversion is complete.
* Conversions should be triggered by a periodic event from a Timer/Counter or
* another peripheral.
*
