    Khaled,

    Please refer section 7.6.1 Interrupt Sources and Interrupt Controller in C6472 data manual to know about the interrupt selection number.

    thank you Senthil
    I'm confused now.
    The code below I have been using it for years to configure the interrupt in .tcf file and as far as I can tell, its working!

    bios.HWI.instance("HWI_INT5").interruptSelectNumber = 18;
    bios.HWI.instance("HWI_INT5").fxn = prog.extern("timer0ISR");
    bios.HWI.instance("HWI_INT5").useDispatcher = 1;
    bios.HWI.instance("HWI_INT6").interruptSelectNumber = 20;
    bios.HWI.instance("HWI_INT6").fxn = prog.extern("timer1ISR");
    bios.HWI.instance("HWI_INT6").useDispatcher = 1;
    bios.HWI.instance("HWI_INT7").interruptSelectNumber = 22;
    bios.HWI.instance("HWI_INT7").fxn = prog.extern("timer2ISR");
    bios.HWI.instance("HWI_INT7").useDispatcher = 1;
    bios.HWI.instance("HWI_INT8").interruptSelectNumber = 24;
    bios.HWI.instance("HWI_INT8").fxn = prog.extern("timer3ISR");
    bios.HWI.instance("HWI_INT8").useDispatcher = 1;


    The content of section 7.6.1 doesn't correspond to the code above. So either I was working with defective code or the question that I asked is incorrect and thus the answer that you provided don't apply.
    Could you please clarify this issue?
    thanks.
    Khaled.

    Hi Senthil,
    I found the problem: its a naming issue. My timer0 is using timer6. Similarly my timer1 is using timer7...
    So all is good.

    thanks.
    Khaled.
