This example generates a sine wave on the buffered DAC output, DACOUTA/ADCINA0 (HSEC Pin 9) and uses the default DAC reference setting of VDAC.
When the DAC reference is set to VDAC, an external reference voltage must be applied to the VDAC pin. This can accomplished by connecting a jumper wire from 3.3V to ADCINB3.
