Signed overflow (crossing the 7F-80 boundary) is detected by the CPU setting the overflow flag.
Unsigned overflow from 255 to 0 is detected by setting the carry flag.
In either case, if the programmer expects either to occur, a branch can be taken depending on the status of the flag after a calculation where overflow could cause a problem.
