  51. * Used to make run-time decisions depending on whether a debug session
  52. * has been active since last reset, ie using a debug probe or similar. In
  53. * some cases special handling is required in that scenario.
  54. *
  55. * @return
  56. * true if a debug session is active since last reset, otherwise false.
