Interrupt Handling

Step 1: Understand interrupt priorities.
Interrupt priorities are assigned based on their hexadecimal locations. Lower the address, higher the priority.

Step 2: Evaluate the priorities based on the locations.
- **D. 002CH:** Highest priority because it's the smallest hexadecimal value.

- **C. 0034H:** Second-highest priority.

- **B. 0024H:** Third priority.

- **A. 003CH:** Lowest priority.

Step 3: Conclusion.
The correct order is D, C, B, A, which corresponds to option (2).
