single-event functional interrupt (SEFI)

A soft error that causes the component to reset, lock-up, or otherwise malfunction in a detectable way, but does not require power cycling of the device (off and back on) to restore operability, unlike single-event latch-up (SEL), or result in permanent damage as in single event burnout (SEB).

NOTE A SEFI is often associated with an upset in a control bit or register.
