Answer :

GinnyAnswer

Final answer:

Interrupt Service Routines (ISRs) manage external events in embedded systems.


Explanation:

Interrupt Service Routines (ISRs) in embedded systems serve the purpose of handling external events or interrupts. They are responsible for responding to signals from hardware devices that require immediate attention, such as timer expirations or data arrivals. By executing specific functions when an interrupt occurs, ISRs help control the flow of program execution in real-time systems.
