//! <h1> Buffered DAC Enable </h1>
//!
//! This example generates a voltage on the buffered DAC output,
//! DACOUTA/ADCINA0 and uses the default DAC reference setting of
//! VDAC.
//!
//! \b External \b Connections \n
//!  - When the DAC reference is set to VDAC, an external reference voltage
//!    must be applied to the VDAC pin. This can be accomplished by connecting a
//!    jumper wire from 3.3V to ADCINB3.
//!
//! \b Watch \b Variables \n
//!  - None.
