9.5.3. Interrupt Masking

Try these first

1. 1.

   What does it mean to mask an interrupt?

   Hint

   Think about prioritizing tasks.

2. 2.

   Give an example of when interrupt masking might be necessary.

   Hint

   Consider urgency of different tasks.

3. 3.

   What is interrupt masking primarily used for?

   • To enable all interrupts
   • To selectively disable interrupts
   • To increase CPU speed

   Hint

   Think about how you manage tasks.

4. 4.

   True or False: Interrupt masking can lead to the ignoring of urgent system errors.

   • True
   • False

   Hint

   What happens if you prioritize one task over another?

5. 5.

   Design a schematic for a system that effectively implements interrupt masking, considering potential hardware components and software requirements.

   Hint

   Think about how you would structure the flow of information within the system.

6. 6.

   Analyze a scenario where the lack of proper interrupt masking leads to system failure. What could be done differently?

   Hint

   Reflect on the implications of cascading failures in system design.
