********************************************************************************
* Detailed Description:
* Initializes eQADC module, performs calibration and cyclically converts PMC
* internal channel as specified by macros CHOOSEN_PMC_ADC_CHNL,
* CHOOSEN_PMC_ADC_SCALE and CHOOSEN_PMC_ADC_COMMAND to check particular voltage
* level, displaying it into terminal window.
* Example configures decimation filter to scale signal down by 1/16, this is
* achieved by FIR filter (user could choose real filter by proper coeficient
* selection).
* Example also sums filtered samples by integrator that is configured to be
* triggered and zeroed by eTPU signal (for simplicity it uses general purpose
* outputs). Integrated values are displayed in terminal window as well.
* No external connection required excluding terminal via eSCI.
