Unassigned bits are set to zero, so an overall value of zero indicates that all tests were passed.
Self-testing is done automatically about 150 milliseconds after power-up or a reset, and the DTEST message will be sent
shortly after the DPOWER message. Subsequently, it is done in response to a TEST command. For the most part, self
testing does not interfere with normal operation. However it will cause brief delays (up to 200 milliseconds) in some
functions, so the test should not be commanded when navigation output is critical.
