) Sign Flag is reset: Result is positive
) Zero flag is set: result is set to zero after the execution of arithmetic or logical operation
) auxiliary carry flag is set: there is a carry from bit D3 to D4
) parity flag is set: result stored in accumulator contain even number of 1’s
) carry flag is result: no carry or borrow bit during the execution of arithmetic operation
