-/** \addtogroup dacc_module Working with DACC
- * \ingroup peripherals_module
- * The DACC driver provides the interface to configure and use the DACC
- * peripheral.\n
- *
- * The DACC(Digital-to-Analog Converter Controller) converts digital code to
- * analog output.
- * The data to be converted are sent in a common register for all channels.
- * It offers up to 2 analog outputs.The output voltage ranges from (1/6)ADVREF
- * to (5/6)ADVREF.
- *
- * To Enable a DACC conversion,the user has to follow these few steps:
- * <ul>
- * <li> Select an appropriate reference voltage on ADVREF </li>
- * <li> Configure the DACC according to its requirements and special needs,
- * which could be broken down into several parts:
- * -# Enable DACC in free running mode by clearing TRGEN in DACC_MR;
- * -# Configure Refresh Period through setting REFRESH fields
- * in DACC_MR; The refresh mechanism is used to protect the output analog
- * value from
- * decreasing.
- * -# Enable channels and write digital code to DACC_CDR,in free running mode,
- * the conversion is started right after at least one channel is enabled and
- * data is written .
- </li>
- * </ul>
- *
- * For more accurate information, please look at the DACC section of the
- * Datasheet.
