CCS/TMS320F28335: Instruction in C to load the value of the Program counter in a variable

Jorge,

Here is how you get the PC value:

1. You can write an assembly file like the one attached. getRPC.asm

2. Extern and call the function in your C code similar to this:

extern uint32_t getRPC(void);

volatile uint32_t lVar;

main(){

...

lVar = getRPC();

...

}

What these steps do is to return the physical address of the first assembly instruction after the PC returns from the function. You can verify the returned balue against the informaiton provided in the disassembly window.

Let me know if you have anymore questions.

Regards,

Ozino
