- Not to be confused with flag value and flag register.
A flag or an indicator bit is a hardware signal that indicates a specific condition or state has been met by a certain component. Flags are often used by subsequent components to determine the course of action that must be taken. Some processors have a dedicated storage space for such flags called a flag register. While a microprocessor might have many internal flags, they are not always made accessible to the software running.
