Negation (Twos-Complement) of Accumulator [r' <- 0 - r]
N The Negative flag is set equal to the new value of the accumulators high-order bit. Z The Zero flag is set if the new value of the accumulator is zero; cleared otherwise. V The Overflow flag is set if the original value was 8016 (8-bit) or 800016 (16-bit); cleared otherwise. C The Carry flag is cleared if the original value was 0; set otherwise.
