1. What is an interrupt used in microcontroller? 2. What is a trigger? 3. What are the two modes of trigger? 4. Explain in detail. What is a thread? 5. Explain in detail. What is a multi-thread system 6. For a general purpose computer, multiple unrelated functions can't perform together. True or false? 7. What is a process when we refer to microcontroller? 8. What does it mean by to arm and disarm a device? 9. Explain. What are: arm a trigger and disarm a trigger. 10. Explain. Why we need to enable and disable interrupts? 11. What C functions shall be called to enable and disable interrupts? 12. Each potential interrupt trigger has a separate arm bit that the software can activate or deactivate. True or false. 13. The software will set the arm bits for those devices from which it wishes to accept interrupts, and will deactivate the arm bits within those devices from which interrupts are not to be allowed. True or false. For most devices there is an enable bit in the NVIC that must be set (periodic SysTick interrupts are an exception, having no NVIC enable). True or false. If it's false, explain. 14. 15. List five conditions that must be true for an interrupt to be generated. 16. For an interrupt to occur, above five conditions must be true at the same time and in exact same order True or false. If it's false, explain 17. Explain. What is a context switch? 18. List complete steps to use a context switch. 19. If a trigger flag is set, but the interrupts are disabled (l-1). How does controller handle this request? (Does controller dismiss/stuck/postponed/etc it?) Explain in detail. 20. Explain. What is an interrupt service routine? 21. Explain. What are interface latency and device latency? 22. What is a real-time system? 23. What factors need to be considered when deciding the most appropriate mechanism to synchronize hardware and software? 24. For extremely high bandwidth and low latency interfaces, should we use interrupt? If yes, give reasons. If not, explain reasons and discuss what else should we use? 25. Explain. What is an atomic operation
