The following controls enable you to step by a single assembly instruction when you are viewing disassembly in the Disassembly tab:
If the assembly instruction makes a function call, RealView Debugger steps into the function.
If the assembly instruction makes a call to a function, RealView Debugger executes the function completely before stopping, unless a breakpoint is met in the function call. Execution then depends on any breakpoint conditions and actions.
