/// \dir
/// !Purpose
///
/// Definitions and methods for using a single external AT73C213 DAC. Several
/// constants must be declared at the board.h level for that:
/// - BOARD_AT73C213_SPI
/// - BOARD_AT73C213_SPI_ID
/// - BOARD_AT73C213_NPCS
/// - BOARD_AT73C213_SSC
/// - BOARD_AT73C213_SSC_ID
///
/// !Usage
///
/// -# Configure the mode register of the SPI associated with the DAC and
/// enable the SPI peripheral (see spi.h).
/// -# Enable the master clock of the DAC (usually, it will be connected to
/// a programmable clock output).
/// -# Call the AT73C213_Enable function with the desired parameters. This
/// function configures the associated NPCS register of the SPI for correct
/// interfacing with the DAC, starts the DAC and configures the SSC.
/// -# Send audio data to the DAC using the SSC, with SSC_WriteBuffer or
/// SSC_Write.
