How to force a 16F628A to reset using PBP statement.

....

Another option is to just jump to location 0. PCLATH=0 followed by @ GOTO 0 works if you
just want to start over from 0.

Bruce,

Could you be a little more specific with your example please?

Thanks,

[Bruce]

Sure. If you want to re-start from location 0, then;

X VAR BYTE

TOGGLE 0

Main:
    FOR X = 0 TO 50
     IF X = 20 THEN
      PCLATH = 0
      @ GOTO 0 ' start over from 0 if X = 20
     ENDIF
    NEXT X
    GOTO Main
    
    END

This isn't exactly the same as a hardware reset, but it's close.

Thanks Bruce.

Since you say that it is not a hard reset but close, will this clear any return addresses in the stack if there is any?


Thanks.

[Bruce]

No it does not clear the stack.
