 		 #134578 - famous last words
Responding to: ???'s previous message
But sir the main reason i dont care about carry is that i am not using it anymore... ;-) and in my whole code you will find that i am not using it....

famous last words. Maybe in a year you will do something to this code and the you will see that after the addition it will have "unexplained faults" that happen about once a week. You will spend days/weeks debugging and finally finf that it is because the ISR when it hits at some place in the main upset the CY.

Oh, well YOU, will, of course, NEVER forget that this ISR changes the CY (cjne)
