NOTE: In addition to this general status information, an extended built-in test (BIT) may be initiated at any time
by entering the “?bit” command. (Extended BIT data is also output whenever the IMU is first powered on.) The
extended BIT provides six bytes of diagnostic data, which are defined in Table 5-12 through Table 5-19.
The constant zero bits are intentionally inserted in the status to prevent it from taking on a
value that, combined with the sequence number and temperature, could be misinterpreted as a
message header code.
