On parts that have multiple EMUD/EMUC pairs (labelled EMUD1/EMUC1, EMUD2/EMUC2, etc...) that is not the case. The pair dedicated for programming is unchangable, and is shared by the base EMUD/EMUC pair. I can't believe nobody here has hit this issue before? I'm beginning to think this is yet another omission in MPLABX, and piece of software I'm quickly learning is REALLY crappy in the minds of many MPLAB customers. I might have to just do I2C by software and forgo using the hardware for that. It sucks, but MCHIP has been making little missteps like this alot lately, so I shouldn't be that surprised.
