Thank you for the response Alex. The function is actually an assembly function that does median filter calculation. I am using a workaround now, having a calculator in front of me to get the value of the twos complement number. But your idea of using a variable makes sense. Will do that going forward.
Is there any way to see the contents of registers as signed integers? The "display as" menu only has "Decimal" and I suppose that works out to be unsigned integer only. Or alternatively, how can I see the register content in the "Quick Watch" windows? Because if this works, I can cast its value to be a "signed int".
