8086 maximum & minimum modes

8086 maximum & minimum modes. The mode is controlled by MN/MX. Maximum mode is obtained by connecting MN/MX to low and minimum mode is by connecting it to high. Having two different modes (minimum and maximum) is used only 8088/8086. Each mode enables a different control structure.
