• One of the special purpose registers is the flag register. Depending on the value of the result after arithmetic or logical operations, the flag bits are changed to 0 or 1.
• The flag register on the 8086 is 16 bits long, with 9 valid flag bits. The flag bits can be divided into two sections. The Control Flags and the Status Flags.
• Flags of Status-After 8-bit or 16-bit operations, six distinct flags of the 8086 are set or reset.
• Flags of Control-There are three separate flags in the 8086 that are used to enable or disable several basic microprocessor activities.
