If the Inventory_flag is set to logic 1, only tags in the READY or SELECTED 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 15693-3.
The INVENTORY READ command can also be transmitted in the addressed or selected
mode (refer to Section "8.4.3.10.3 Addressed and selected mode").

If the option flag in the request is set to 1 the response contains the truncated or

If the option flag in the request is set to 0 the UID is not part of the response.

The 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 UID is requested in the truncated format the re-transmitted UID can be calculated
as follows:
16 slots: 64 - 4 - mask length rounded up to the next byte boundary
1 slot: 64 - mask length rounded up to the next byte boundary
Example: mask length = 30
Returned: 64 - 4 - 30 = 30 gives 4 bytes

8.4.3.10.3 Addressed and selected mode
The INVENTORY READ command can also be transmitted in the addressed or selected
mode. In this case the Inventory_flag is set to 0 and the meaning of flags 5 to 8 is in
accordance with table 4 in ISO/IEC 15693-3.
In the addressed or selected mode the INVENTORY READ command behaves similar to
a READ or READ MULTIPLE BLOCK command.
In the addressed mode it is recommended to address the label IC with a mask length of
64 and to transmit the complete UID in the mask value field.

In the selected mode (label IC has been selected with a valid SELECT command before)
it is recommended to address the label IC with a mask length of 0 (and do not transmit
the mask value field).
Remark: If the INVENTORY READ command is used in the addressed or selected
mode, the AFI shall not be transmitted and the label IC will only respond in the first time
slot.
9.5.3.11 FAST INVENTORY READ
Command code = A1h
When receiving the FAST INVENTORY READ command the ICODE SLIX2 IC behaves
the same as the INVENTORY READ command with the following exceptions:
The data rate in the direction ICODE SLIX2 IC to the interrogator is twice that defined in
ISO/IEC 15693-3 depending on the Datarate_flag 53 kbit (high data rate) or 13 kbit (low
data rate).
The data rate from the interrogator to the ICODE SLIX2 IC and the time between the
rising edge of the EOF from the interrogator to the ICODE SLIX2 IC remain unchanged
(stay the same as defined in ISO/IEC 15693-3).
In the ICODE SLIX2 IC to the interrogator direction, only the single subcarrier mode is
supported.
9.5.3.12 SET EAS
Command code = A2h
The SET EAS command enables the EAS mode if the EAS mode is not locked. If the
EAS mode is password protected the EAS password has to be first transmitted with the
SET PASSWORD command.
The timing of the command is write alike.
Option 0 (Option flag not set) is supported.
Option 1 (Option flag set) is supported.
