This option sets the start point for a range of addresses for which trace of program instructions and data accesses are captured. When you select this option, an arrow is placed in the left margin, next to the line of code you have selected.

After you have set a start-range point, the corresponding end-range point, End of Trace Range (Instruction and Data), becomes available in the List Selection dialog. No other range-setting options are available until after you select an associated end-range point. When you set an end-range point, an arrow is placed in the left margin next to the line of code you have selected

  When you set a trace range, any branches to memory outside the range that you set are not captured. These branches are represented as Trace Pause status lines in the Analysis window. To ensure that trace capture includes any data and memory accesses that might be branched to, you must use the options Trace Start Point and Trace End Point.

If you do not set the end point for the range, the default end point will be used, that is, 0xFFFFFFFF.
