Stack pointer

Eric_t — Fri, 07 Dec 2012 09:25:57 GMT

Hi everybody,

I am using HCS12 controllers and Codewarrior v3.1.

Is it possible to read the current position of the SP and put it in a integer variable?

Thanks

Nikos

Hello Nikos,

you can, for example, try this:

/*declaration*/

unsigned short oldsp;

...

/* save current SP */

asm {

STS oldsp

}

...

Best Regards.
