ICODE 3 (TagTamper)

Extended Mode

If the most significant bit of the Mask Length byte is equal to 1, the response format is defined by the extended

option byte.

The request contains:

• Flags

• Inventory Read command code

• IC Manufacturer code

• AFI (if the AFI flag is set)

• Mask length (most significant bit equal 1)

• Extended Options

• Mask value (if mask length > 0)

• First Block Number, if specified in extended options byte

• Number of Blocks, if specified in extended options byte

• CRC 16

Table 85. Inventory Read (extended mode) request format

If the Inventory_flag is set to logic 1, only tags in the READY or SELECTED state respond (similar behavior as

INVENTORY command). The meaning of flags 5 to 8 is in accordance with table 5 in ISO/IEC 15693-3 [3].

The INVENTORY READ command can be transmitted in the addressed or selected mode also ( Addressed and

selected mode ).

Bit number Bit name

Value Feature

Label responds independent from the EAS status

1 (LSB)

EAS_MODE

Only labels will respond which have the EAS enabled

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)

CID_COMPARE

No CID is transmitted in the command

16 bit CIDwill be transmitted in the command and only labels with the same CID

will respond

CID_RESPONSE 0

CID will NOT be transmitted in the response from the label

CID will be transmitted in the response from the label

Tag 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 are requested from the tag, first block number byte and

number of blocks byte shall not be transmitted in the command
