Internal BITE Packet
RCP8 can optionally generate an internal BITE packet. These bits convey additional status information that is not contained in the other transmission formats. The shutdown status of RCP8 (up to 32 different conditions) is contained in the first five bytes. The last five bytes hold other miscellaneous information. The identification byte is selectable to avoid conflicts with other BITE packets.
