Magnus: See the email I just sent you. Pinnacle doesn't currently explicitly support the features of the Atmel line. While you can use a header file to define the additional SFRs and assemble working programs, you still won't be able to simulate it correctly since that requires underlying support in the Simulator.

We plan to add support for the Atmel line soon. We're currently working on a 32-bit version and Atmel support will be the first order of business after the 32-bit version is complete.
