ALU of 8085 have 5 flip flops whose states (set/reset) are determined by the result data of different registers and accumulator. They’re called as Zero, Carry, Sign, Parity and Auxiliary-Carry flags. Zero Flag (Z): when an arithmetic operation leads to zero , the flip-flop referred to as the Zero flag – which is set to 1.
