Challenge Problems
Push your limits with challenges.
Question 1
Design a microcontroller system that uses both external and timer interrupts. Explain how you would configure the IE and IP registers to ensure timely responses to both sources.
💡 Hint: Consider how to manage timing and responsiveness.
Question 2
Evaluate a scenario where an external interrupt is enabled but a higher priority timer interrupt occurs simultaneously. Detail the precedence of execution based on your understanding of interrupts.
💡 Hint: Think about how the interrupt vectors would handle the situation.
