If the Inventory_flag is set to 1b, only NTAG 5 link in the READY or SELECTED

(SECURE) state will respond (same behavior as in the INVENTORY command). The

meaning of flags 5 to 8 is in accordance with table 5 in ISO/IEC 15693.

The INVENTORY READ command can also be transmitted in the addressed or

SELECTED mode (see Section 8.2.3.5.1.3).

go to QUIET state after response

NTAG 5 link will add the user memory blocks in the response

as requested with first block number byte and number of blocks

byte in the command

SKIP_DATA

No user memory data is requested, first block number byte and

number of blocks byte shall not be transmitted in the command

Custom ID (CID) will be NOT transmitted in the response

CID_RESPONSE

Custom ID (CID) will be transmitted in the response

No CID is transmitted in the command

CID_COMPARE

16-bit CID will be transmitted in the command and only NTAG 5

link with the same CID will respond

UID will be transmitted as in regular mode (truncated reply

depending on least significant 7 bits value of mask length and

the mask value)

UID_MODE

Complete UID will be transmitted (independent from mask

length)

NTAG 5 link responds independent from the EAS status

EAS_MODE

Respond only, when EAS is enabled

If the Option_flag in the request is set to 1b the response contains the truncated or

complete UID depending on the extended option UID_MODE bit.

If the Option_flag in the request is set to 0b the UID is not part of the response.
