RE11 and RE17 govern this, and connecting to the I2C bus sounds promising, but I don't know enough of your application to say anything with certainty. This would be worth an official Q&A.

That said, what on earth are you doing that one Core Device Interface Module (let alone that RE07 lets you use two) isn't enough?!
