Your question is Understanding Interrupt Service Routines in Embedded Systems. Take a moment with it on the right.
Talk me through your thinking if you like. When you're confident, submit your answer and I'll grade it like a real screen (7/10 or better passes).
What is the role of an Interrupt Service Routine (ISR) in embedded systems? Discuss how ISRs handle interrupts, their execution context, and their impact on system performance. What are some common challenges associated with ISRs?
