2.4. ARM Cortex-M0 Interrupt System

Try these first

1. 1.

   What does NVIC stand for?

   Hint

   Think about the structure of the controller.

2. 2.

   How many interrupt sources can NVIC manage in the ARM Cortex-M0?

   Hint

   Recall the number mentioned during our sessions.

3. 3.

   What does NVIC stand for?

   • Nested Vectored Instruction Controller
   • Nested Vectored Interrupt Controller
   • Non-Vector Interrupt Controller

   Hint

   Focus on the role it plays in managing interrupts.

4. 4.

   True or False: SysTick is used for context switching.

   • True
   • False

   Hint

   Recall the specific function each interrupt serves.

5. 5.

   Design an embedded system that requires multiple interrupts with different priority levels. Explain how the NVIC would handle these interrupts.

   Hint

   Think about critical and non-critical inputs.

6. 6.

   How would the lack of a well-functioning NVIC affect a real-time application like a medical device?

   Hint

   Consider the implications of priority management.
