Hello,

I'm using SPC5 studio with the high-tec tool chain for SPC56EL70L5. I'd need to set the linker in such a way that one out of 32 general purpose register won't be never used by the compiler because I need it for some assembly code lines. Could you tell me what kind of directives do I have to use?

Thank you in advance for the help

Hello Stefano ,

i do not know if Hightec can handle that.

the simplest way is to Save/Restore registers that you use ..

Best regards
