Types of Flags in 8086
How do flags influence program execution on the 8086 microprocessor?
The need for flags arises as decisions have to be made during the execution of a program. Conditional jump instructions are utilized for checking them so that the control flow of the program may be determined under specific conditions.
How are instructions for string manipulation altered by the Direction Flag?
The transfer of data s direction is affected by the direction flag which determines whether string operations such as move byte from string (MOVSB) and scan byte of string (SCASB) increase or decrease the source and destination pointers.
How does the Trap flag impact things for the 8086 processor?
In debugging, the Trap flag is used to move slowly step-by-step through instructions, so it can be analyzed properly. Then, each instruction sets it, which in turn causes the CPU to create a trap after executing one instruction.
