I looked at it and i cannot get clear in which circumstances, this is, but it does not really matter i suppose. Point is, you cannot destroy the value of the Tbit at your liking, although i never saw the Tbit being used in my code by gcc.
And how about the H flag? The Half carry is produced by a lot of instructions, but i never saw the compiler test for it,or make use of it. I looked the avr directory over for H flag tests or direct H flag manipulating functions (seh, clh, brhc, brhs) and found none. You would really help me if you know more on this.
