“Not used” bits are always set to 0. The bits may be set as errors are detected. But these errors are not reported from “continuous back-
ground self-testing”, but rather through “observation” of various conditions during normal operation. That is, no actual “self testing” is being
“continuously” performed. But as errors are detected during normal operation, these will be reported.
