Hello Oleg.

This routine will surely do the trick you are looking for.

I have used it myself and it works perfectly.

After executing this routine the PC will have been loaded with 0000h, so a reset is in effect. PC will get the address stored in the stack and then it will jump to it because of the reti instruction.

You might want to use a routine that will clear some registers. That can be done before or after the reset, depending on what your program does. Always set the SP register after reset to a specific value, or else you will be in serious debugging trouble.
