Data storage format identifier (DSFID)
The data storage format identifier indicates how the data is structured in the LRIS2K
memory. The logical organization of data can be known instantly using the DSFID.
It can be programmed and locked using the Write DSFID and Lock DSFID commands.
CRC
The CRC used in the LRIS2K is calculated as per the definition in ISO/IEC 13239.
The initial register contents are all ones: FFFFh.
The two-byte CRC are appended to each request and response, within each frame, before
the EOF. The CRC is calculated on all the bytes after the SOF up to the CRC field.
Upon reception of a request from the VCD, the LRIS2K verifies that the CRC value is valid.
If it is invalid, the LRIS2K discards the frame and does not answer to the VCD.
Upon reception of a request from the LRIS2K, it is recommended that the VCD verifies
whether the CRC value is valid. If it is invalid, actions to be performed are left to the
discretion of the VCD designer.
The CRC is transmitted least significant byte first.
Each byte is transmitted least significant bit first.
