Hi all, can anybody suggest how to implement SWI without DSP/BIOS on c6711. I did't find any interrupt vector location to map a SWI. I implemented this way, I mapped interrupt selector value 10 ( No default event mapping for this one, given as reserved) to INT15. This INT15, i configured to SWI. Whenever i want to trigger my SWI, i am setting the flag corresponding to int15. I think its working ok. But in future if this perticular interrupt selector value 10, is mapped to some peripheral as default. Then it may be difficult to use that peripheral or SWI may be triggered by that peripheral. I feel its not good practice do as above. Can anybody suggest good method to implement a SWI or guide me to a document which describes it. Thanks in advance ===== BHASKAR REDDY .

I'm not sure I understand what you're trying to do. Anyway, SWI is a DSP/BIOS artifact, that is, purely software and there isn't a vector interrupt associated to it. The name may lead to misinterpretation. If you want to use it in your code, you have to include <swi.h> and probably lots of other header files. Or, use the CCS configuration tool, which for me is the best approach. -----Mensaje original----- De: neeli bhaskar reddy [mailto:] Enviado el: viernes, 05 de noviembre de 2004 3:54 Para: Asunto: [c6x] SWI without DSP/BIOS on 6711 Hi all, can anybody suggest how to implement SWI without DSP/BIOS on c6711.
