8.1.3.8 Get multiple block protection status
Command Code = B8h
To the Get Multiple Block Protection Status command the label responds with the block
protection status of the requested blocks.
Remark: If the sum of the first block number and the number of blocks exceeds the total
available number of user blocks the number of transmitted security status bytes is less
than the requested number, which means that the last returned status byte is the one
corresponding to the highest available user block, followed by the 16-bit CRC and the
EOF.
