Hi Brad, I'm not an expert in assembly level. Not sure why you want to use assembly to process a C variable. I will suggest you refer to section 6.6.2 and 6.6.3 of the TI Arm Compiler User's Guide for Accessing Assembly Functions/Variables From C/C++. Also refer to section 5.8 for Register Variables and Parameters. Register is a standard C keyword that allows you to force allocate a variable to a register if optimization is not enabled.
