Hello All I was hoping some of you could help me write an interrupt vector. I'm using CCS - Should I be using something else?. I understand how the IV works, but I would be better helped if some of you have a well commented example of this... Please help!. Best Regards Daniel-San |

Writing an interrupt vector?

Daniel-San vectors.asm is an example of interrupt vector. myFunction1(2-3) are functions that are declared in other files the no_isrxx finctions are infinite loops so that if an unexpected IT occurs, you will get it easily you need also to set the IVPD and IVPH register. insert the 2 following lines in your initializations phase (using algebraic assembly) @IVPD_L = #(_myVec >> 8 ) || mmap() ;init IT vector @IVPH_L = #(_myVec >> 8 ) || mmap() ;init IT vector Hope this helps, good luck Laurent >From: >Reply-To: >To: >Subject: [c55x] Writing an interrupt vector? >Date: Wed, 9 Oct 2002 11:25:05 +0200 >Hello All > >I was hoping some of you could help me write an interrupt vector.
