Variables declared in the global scope of the LP-Core program reside in either the ``.bss`` or ``.data`` section of the binary. These sections are initialized when the LP-Core binary is loaded and executed. Accessing these variables from the main program on the HP-Core before the first LP-Core run may result in undefined behavior.
