* Detailed Description:
*
* eQADC mode: Continuous scan with external trigger.
* Periodic trigger from eMIOS_0 ch16.
* ANA ch5 is converted and result is sent to RFIFO0.
*
* eMIOS ch0 duty cycle is modified based on result data, so LED is dimming
* if connected to eMIOS ch0 output.
*
* ADC result is also displayed on terminal each second.
