Question 1

What is the primary function of an Interrupt Service Routine (ISR)?

  • To manage device priorities
  • To execute the main program
  • To handle interrupts

💡 Hint: Think about the role ISRs play in interrupt handling.

Question 2

True or False: Lower priority interrupts can always interrupt higher priority interrupts.

  • True
  • False

💡 Hint: Consider how priorities are assigned in interrupt handling.

Challenge Problems

Push your limits with challenges.

Question 1

Given a scenario where multiple interrupts occur, construct a logical flowchart detailing how the CPU should prioritize each interrupt based on pre-assigned priority levels. Include considerations for context switching.

💡 Hint: Think about how interrupts must be sequenced and the importance of context.

Question 2

Analyze how neglecting to manage interrupt flags could impact overall system performance in a multi-device setup. Propose a solution to mitigate potential issues.

💡 Hint: Consider how interruptions can lead to lost events if not managed correctly.
