How many flags are there in 8086 microprocessor

How many flags are there in 8086 microprocessor and what are they?

What is a Flag : 

it is one bit signal which may have only one two values 1 0 or true false. When set flag termed as set is in position 1 and in 0 position it is termed as reset.

Flag Register : 

A 16 bit memory storage which stores all the flag bits. There are total 9 flags , 3 are control flags and 6 act as status flags other bits are spare.

Control Flags ,

 these flag control some specific operation of 8086, following are three control flags. With the help of these flag, 8086 controls some of its operation. The control flags are:

Control Flags -Interrupt Flag , Trap Flag and Direction Flag, 

Status Flags-  sign flag, zero flag, parity flag, carry flag, Auxiliary carry, Overflow flag

Flag Symbol	Flag name	Description
S	Sign flag	Set when answer of computation is negative
Z	Zero	Set when computation or comparison of previous instruction is zero
P	Parity	Set when lower byte contains even number of ones
C	Carry	When there have carry in computation
T	Trap	When processor enters single step instruction mode
I	Interrupt	Maskable interrupts are recognised
D	Direction	In string manipulation instructions.If 0 string is processed lowest to highest address,if 1 highest to lowest address
Ac	Auxiliary carry	Set if there is carry from lowest nibble
O	Overflow	When result is larger to accommodate in registers
