Question 1.
What does NVIC stand for?
Show hintHide hint
Think about what type of controller is used for managing interrupts.
Question 2.
How many priority levels does the NVIC support?
Show hintHide hint
Consider the levels of urgency in handling various events.
3Question 3.
What is the main purpose of the NVIC?
- To handle memory access
- To manage interrupt requests
- To manage power consumption
Show hintHide hint
What do you think it generally controls?
4Question 4.
True or False: The ARM Cortex-M0 supports both preemption and non-preemption of interrupts.
- True
- False
Show hintHide hint
Think about how interrupts can be managed in time-sensitive situations.
Question 5.
Design a small application that requires multiple interrupts, including a high-priority interrupt for emergency signals. Describe how you would implement the NVIC.
Show hintHide hint
Consider how critical tasks can be prioritized over others in your application.
Question 6.
Given a scenario where a low-priority task is interrupted by a higher-priority task that itself gets interrupted by another high-priority task, explain how the NVIC manages this situation.
Show hintHide hint
Think about how the NVIC queues and manages incoming interrupts.
