Different Types of Control Flags for the 8086

The 8086 microprocessor uses several types of control flags to manage its operations and control the execution of instructions. These flags are part of the processor’s flag register, which indicates the current state of the processor and influences its behavior. The control flags are the indicators that count the successful attempt or a failed attempt through each module. These types of flags are also applied to all module types. In this article, we have discussed the different types of control flags for the 8086 in detail.

What is Control Flag?

A control flag is a specific bit within a special register. These are the FLAGS or status register that is used to control the operation of the CPU. These flags determine certain modes of operation. It also enables or disables specific CPU functions, and influence the behavior of instructions. Control flags are essential for managing how the microprocessor interacts with instructions and the system as a whole....

Keypoints Related To Control Flags for the 8086

Flag Bit Function DF This is one type of directional flag which is used in string related operations. D = 1 represents the situation when the string access to lower memory address from higher memory address.If D = 0, the process will be reverse. IF This is an interrupt flag. I = 1 means the MPU will recognize the interrupts from peripherals. I = 0 means the interrupts will be ignored for the particular process. TF This a trap flag which is used to perform the on-chip debugging. T = 1 when the process will work in a single step mode.After every instruction, one internal interrupt will happen for sure. This interruption will help to execute the programs instruction by instruction....
