The RECEIVE DIAGNOSTIC RESULTS command transfers the results of the
diagnosis specified by the SEND DIAGNOSTIC command to INIT. The
RECEIVE DIAGNOSTIC RESULTS command is issued following the SEND
DIAGNOSTIC command. If the command does not follow the SEND
DIAGNOSTIC command or if there is no data to be transferred, the command
ends normally without transferring any data.

The WRITE BUFFER command downloads firmware to flash ROM.
Mode must be set to 5. Otherwise, the command responds with Check Condition.
DIML must be set to 0.
If TNFY is 0 and Allocation Length is not 0, the command transfers the data to be
written to flash ROM to the data buffer, checks the data for validity, then writes it
to flash ROM. If TNFY and Allocation Length are both 0, the command checks
the data in the data buffer for validity and writes it to flash ROM. If TNFY is 1,
the command transfers the data to be written to flash ROM to the data buffer.
Code-ID specifies the type of code to be downloaded.
Allocation Length specifies the length of data to be transferred, in bytes.
Buffer Offset specifies the offset of the data to be transferred.
If the writing to flash ROM ends abnormally, the command responds with Check
Condition.
If a power failure occurs or an interface cable is disconnected during
downloading, flash ROM data is not guaranteed.
