1. An algorithm, which is correct, does not produce correct results when interrupts are enabled. What could be the reason for this and how will you ensure that the algorithm works correctly when interrupts are enabled. (5 marks) 2. How will you ensure that the system does not lock up when interrupts are used. (5 marks) 3. Develop a mikroC program tocontrol an LED using an LDR. The LED should be turned off when the light intensity is greater than or equal to 80% of the LDR output otherwise it should be turned on. Your code should be commented to reflect your ideas (20 marks) 4. Simulate your code using Proteus. (20 marks)
