Could you pleas Let me know with regards REFCON register setting in case of internal and external when using ADC0 to ADC9.

I see there a difference in different Discussion here on Engineering Zone .


Some say when using Internal REFCON = x01 and data sheet states REFCON =0x0 ,

and when using External REFCON =0x3 and data sheet says REFCON = 0x1


Which one is correct both seem to work without any problem on the evaluation board .


Thanking you

With best regards and wishes
