Check CPU integrity

Hi,

Does ST have function to check the CPU integrity?

I need that kind of function on startup to check if the CPU flags (overflow...) are valid.

Normally, these are asm function.

Does that kind of function exist?

Thanks

Frank

Does any one knows how to generate an overflow ?

CPU : STR712F

I tried this but it does not work:

__asm (''MOV R1,#0xffffffff \n'');

__asm (''MOV R2,#0xffffffff \n'');

__asm (''MOV R3,#0xffffffff \n'');

__asm (''ADDS R2,R1,R3 \n'');

__asm (''MOV R2,#0xffffffff \n'');

__asm (''ADCS R2,R1,R3 \n'');

__asm (''BVC cpu_errors \n'');

__asm (''BVS exit \n'');

Thanks
