I'm currently developing a system using Parallax's Clearview 16CXX (ver. 2.0) in-circuit emulator. All development is done through PDE ver. 2.04 emulating a PIC16C74. The problem is I am unable to write to data memory above 0BFh using INDF. I have stepped through the code. The FSR is being set properly, but any writes to the INDF result in nothing happening. I am suspicious that the emulator is somehow stuck in thinking it has the limitations of a 16C72 (which has no data memory above 0BFh). I have double-checked the device line in the code and made sure the device was set to 16C74 within the project information. Has anyone else encountered such a problem? Regards, Vincent Deno
