I did that. I set the page size to 1024 bytes. The two functions SetPage() and GetPage() are still greyed out with no button to 'generate code' next to them.
So, I investigated a little deeper and decided to look at the generated code iin IEE1.c. Guess what? The code was generated and is in the file. So, the instructions are not clear, or this is a bug.
Setting the page size to non-zero automatically generates the code for SetPage and GetPage functions.
Maybe the Processor Expert team should fix this discrepency.
