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.
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.
