The WRITE BUFFER command downloads the firmware to the flash ROM.

Mode must be set to 5. Otherwise, the command responds with Check Condition.

If TNFY is 0 and Allocation Length is not 0, the command transfers data to be written on the flash ROM to the data buffer. The WRITE BUFFER command checks for validity of transfer data, then writes it on the flash ROM.

If TNFY is 0 and Allocation Length is 0, the command checks propriety of data on the data buffer and writes on the flash ROM.

When TNFY is 1, the command transfers data to be written on the flash ROM into the data buffer.

Code-ID indicates the type of code to be downloaded.

Allocation Length indicates the length of data to be transferred in bytes.

Buffer Offset indicates the offset value for data to be transferred.

If write operation to the flash ROM ends abnormally, the command responds with Check Condition.

If power failure or interface cable disconnection occurs during downloading, flash ROM data may not be assured.

Valid download data is Fujitsu distributed data only.
