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.
