Processor Header File Need Proper Defs For 16 Bit Sfrs in Enhancement Requests Posted January 26, 2013 · Report reply Thanks for the "All Warnings" tip. I'll check that out. Using SourceBoost IDE. I don't understand the comment about "other pics". This is the header file for an 18F2620. I don't see why the header file for a specific processor should be influenced by what another processor has. Same for all the 16 bit registers. I was able to get around it, but I really don't see why every user that wants to use one of the 16 bit registers has to treat them as two 8 bit registers, or define his own variable.
