* Detailed Description:
* This example shows how to use the back-to-back mode of the PDB to trigger
* sequence of ADC channels conversion. 4 PDB channel pre-triggers/triggers are
* generated upon single PDB SW trigger. The first trigger is started by the PDB,
* no delay is used. Next 3 triggers start after corresponding acknowledgment is
* received from ADC.
* DMA is configured to read the ADC result registers.
* Within DMA major interrupt the new conversion scan is started via PDB SW request.
* Converted data is used to change color of the EVB led based on Trimmer position.
