Problem passing variable to function in ISR

Jeremy Brookley

So, I have a problem sending a value to a function at different parts of my code. Here is my code:

void LongRightShift(unsigned char NumBitsShift)
{
// My Code Here
     NumBitsShift = NumBitsShift; // So you can place a breakpoint here and read NumBitsShift
}

Now, when I call

LongRightShift(2);

in the main part of my program, NumBitsShift = 2. When I call it in the Decimator2_ISR, NumBitsShift = 1;

Does this have to do with the way I'm passing it or is there a conflict with running other functions in an ISR?

Any help you can give me would be appreciated. Thanks!

    I just realized that the lower the setting, the less optimization. I guess I misunderstood the optimization ratings because setting the number lower makes my code bigger. Which is concerning, already being at 7k . . . :p

    I guess I have a lot more optimization in my code than I realized. That might explain a few things . . .
