What refers to the set of commands used for programming microcontrollers?

The term that refers to the set of commands used for programming microcontrollers is "Instruction Set." An instruction set is a collection of machine language commands that a microcontroller can understand and execute. This set defines how the microcontroller interacts with both the software and hardware, enabling developers to perform operations such as data processing, control logic, and input/output management.

Each microcontroller architecture has its own distinct instruction set that determines how developers can leverage the microcontroller's capabilities effectively. Understanding the instruction set is crucial for programming, as it shapes how software can be structured and how efficient the code can be in executing tasks.

While other terms like "Control Set," "Microcontroller Set," and "Signal Processing Set" might sound relevant, they do not specifically describe the fundamental commands or instructions used for microcontroller programming. The "Control Set" does not refer to a recognized category in microcontroller terminology; "Microcontroller Set" is too vague, and "Signal Processing Set" relates more to the processing of signals than to the programming of microcontrollers. Thus, the "Instruction Set" is the precise term used in the context of microcontroller programming.
