Challenge Problems
Push your limits with challenges.
Question 1
If the CPU is currently executing a sequence of instructions and processes a hardware interrupt request, outline the steps it follows in sequential order and discuss potential pitfalls of skipping any steps.
💡 Hint: Reflect on why context matters when dealing with pending interrupts.
Question 2
Consider a microcontroller in a robotic arm application that must react instantly to safety shutdown signals. Describe how you would implement the interrupt handling for safety signals, outlining each step and discussing how you would ensure efficiency.
💡 Hint: Consider the priorities of different interrupts.
