Jan, I agree with you any time I copy and paste the code gets messed up so to make it faster I remove those comments assuming same line repeated it wouldn't be hard to understand. Thank you Andre -----Original Message----- Andre, do *not* take this personaly, it's just a after-a-Friday-evening-beer-comment :-) In your HI_ISR code (24 lines of C code) I found *one* single line comment, this one: CLRWDT(); // clear WDT Couldn't have said it better myself ! :-) :-) Have a nice Friday Evening everyone !
