Ionizing radiation need not trigger unintended self-testing. Protocols installed in certain microcircuits permitting functional self-testing do not consider possibility of inadvertent triggering by protons or energetic heavy ions in space or satellite orbit. Recommended devices be rendered immune to so-called single event effects of energetic ions in cosmic rays, flares, or trapped-charge belts surrounding Earth and some other planets. Proposed pair of stimuli be applied to device in specified manner to start self-test. Protocol can require two or more stimuli at single node, or pair of stimuli at two nodes, or some more complicated combination.
