Functional Specification
If the Option flag in the request is set to 0 the response contains:
The I
mechanism and timing of the Inventory read command performs the same as at the Inventory command
which is described in Clause 8 of ISO/IEC 15693-3.
If the Option flag in the request is set to 1 the response contains:
The I
bytes of the UID, which are not parts of the mask and the slot number in case of 16 slots, are returned.
Instead of a padding with zeros up to the next byte boundary the corresponding bits of the UID are returned.
The mechanism and timing of the Inventory read command perform the same as at the Inventory command
which is described in Clause 8 of ISO/IEC 15693-3.
Note: The number of bits of the re-transmitted UID can be calculated as follows:
Note: If the sum of first block number and number of blocks exceeds the total available number of user

CODE SLI IC reads the requested block(s) and sends back their value in the response. The
CODE SLI IC reads the requested block(s) and sends back their value in the response. Additionally the
blocks the number of transmitted blocks is less than the requested number of blocks, which means
that the last returned block is the highest available user block, followed by the 16 bit CRC and the
EOF.
16 slots: 64 - 4 - mask length rounded up to the next byte boundary
