What is required for Top Down debug mode to function correctly?

For Top Down debug mode to function correctly, it requires an Entry Point. The Entry Point serves as the starting location for the debug process, allowing the system to identify where to begin the debugging sequence. This is essential for tracking the flow of data and behavior of the application, contributing to a comprehensive understanding of how the system operates from that specific point onward.

The other requirements do not serve the same function as an Entry Point. A specific PID identifies a process but does not determine where debugging will start. A running instance of the application is indeed necessary for the debug process, but without an Entry Point, it lacks direction. Similarly, a predefined IP Address might be relevant in a networking context but does not play a role in the directional aspect of the debugging process in Top Down mode. Hence, an Entry Point is critical for initiating and guiding the debugging session effectively.
