After executing ADD A, #80H with A initially containing 90H, what are the states of the Carry (C) and Overflow (OV) flags?

Question

Accepted Answer

C=1 (unsigned overflow: 0x90+0x80=0x110, result > 0xFF), OV=1 (signed overflow: -112+(-128) should be -240, but result appears as +16)

Answer

C=1 (unsigned overflow), OV=0 (no signed overflow)

Answer

C=0, OV=0 (no overflow in either unsigned or signed arithmetic)

Answer

C=0 (no unsigned overflow), OV=1 (signed overflow occurred)
