Challenge Problems

Push your limits with advanced challenges

Challenge 1 Hard

Design a simple assembly program for the 8085 that uses both hardware and software interrupts. Detail how the interrupts are triggered and handled.

💡 Hint: Integrate example scenarios, like toggling an LED with a button press and handling timer signals.

Challenge 2 Hard

Explain the importance of priority in handling multiple interrupts. What happens if two interrupts occur at the same time in an 8085 system?

💡 Hint: Recalling the fixed hierarchy of the 8085 will aid in your explanation.
