How to insert machine code in source code?

Simon Z

Hello,

For the test purpose, I want to insert some machine code in my source code? Is it possible?

Thanks,
Simon

    Hello,

    This should work:

    void RunThisWeirdOpCodeJustForCuriosity(void) {
 __asm
 {
   DB XX        ;   replace XX, YY with some opcode - e.g. undefined :-) for your MCU
   DB YY
 }
}

    Useful to test the trap while attempting to execute an illegal instruction, e.g.

    P.S. Keep 2 instructions there to make code aligned at even addresses of your target - C16x needs it.

    Regards,
    Nikolay.
