In embedded systems, interrupts play a crucial role in managing the flow of execution and responding to external events in a timely manner. When an interrupt occurs, the processor temporarily stops its current task to handle the interrupt request. This allows the system to promptly respond to events such as sensor inputs, timer expirations, or communication requests without delaying critical operations.

Interrupts are classified into different types, such as external interrupts from hardware peripherals and internal interrupts from software. Each type serves specific purposes, such as triggering a response when a button is pressed or when a data packet is received over a communication interface.

Understanding interrupts is essential for embedded systems developers, as they need to design systems that can efficiently handle various events while ensuring the system's real-time performance. Embedded certification courses often cover topics related to interrupts, providing developers with the knowledge and skills needed to design and optimize embedded systems effectively.
