the designer wont let me configure 4 channels of 5v ref ADC. it states the max 3.3v.
When I asked at the meeting about this it was mentioned it supported it. So I suspect I am missing something specific to the pioneer board.

Hi Michael,
This is probably happening because your system supply is set to 3.3v.
You can change you system to 5.5 and then the ADC option will allow a higher VRef as well.
To do this:
1. double-click your design's .cydwr file to open the system configuration
2. In the 'system' tab change your operating voltage to 5v
3. Back in the SAR ADC config, you can now select the 5v reference
