WebFeb 11, 2024 · The diagram below summarizes the 8086's flags. The overflow, sign, auxiliary carry, and carry flags were discussed above. The zero flag simply indicates that the result of an operation was zero. The parity flag counts the number of 1 bits in a result byte and the flag is set if the number of 1 bits is even. At the left are the three control flags. WebIn 8086 the overflow flag is set when _____. a. the sum is more than 16 bits: b. signed numbers go out of their range after an arithmetic operation: c. carry and sign flags are set: …
