-/**
- * \file
- *
- * \section Purpose
- *
- * Interface for configuration the Analog-to-Digital Converter (AFEC) peripheral.
- *
- * \section Usage
- *
- * -# Configurate the pins for AFEC.
- * -# Initialize the AFEC with AFEC_Initialize().
- * -# Set AFEC clock and timing with AFEC_SetClock() and AFEC_SetTiming().
- * -# Select the active channel using AFEC_EnableChannel().
- * -# Start the conversion with AFEC_StartConversion().
- * -# Wait the end of the conversion by polling status with AFEC_GetStatus().
- * -# Finally, get the converted data using AFEC_GetConvertedData() or
- * AFEC_GetLastConvertedData().
