9.8. Nested Interrupts and Interrupt Controlling

Try these first

1. 1.

   What is a nested interrupt?

   Hint

   Think about priority levels.

2. 2.

   What role does the stack play in nested interrupts?

   Hint

   Consider how you keep track of multiple tasks.

3. 3.

   What allows a higher-priority ISR to interrupt a lower-priority ISR?

   • Stacking
   • Nesting
   • Masking

   Hint

   Think about which term refers to the hierarchy of interrupts.

4. 4.

   True or False: Interrupt priority masking allows lower-priority interrupts to interrupt higher-priority ISRs.

   • True
   • False

   Hint

   Consider how priorities work.

5. 5.

   Design a simple system that utilizes nested interrupts for a robotics application, detailing how you would prioritize tasks.

   Hint

   Consider real-world scenarios where safety is key.

6. 6.

   Describe a scenario where poor stack management could lead to system failure in a nested interrupt environment.

   Hint

   Think about the importance of keeping track of multiple tasks.
