Challenge Problems

Push your limits with advanced challenges

Challenge 1 Hard

If an 8085 microprocessor has its TRAP interrupt signaled, what should be the CPU's course of action, and how does it affect running programs?

💡 Hint: Think about how urgent calls require action but don't cut off your current task immediately.

Challenge 2 Hard

In a practical application scenario, illustrate a situation where maskable interrupts could lead to issues if not managed correctly in an 8085 microprocessor system?

💡 Hint: Consider how delay in data might cause larger problems, especially in real-time systems.
