ICODE SLIX-S
8.4.3.10 ENABLE PRIVACY
Command code = BAh
The ENABLE PRIVACY command enables the ICODE SLIX-S Label IC to be set to
Privacy mode if the Privacy password is correct. The ICODE SLIX-S will not respond to
any command except GET RANDOM NUMBER and SET PASSWORD.
The XOR password has to be calculated with the password and two times the received
random number from the last GET RANDOM NUMBER command:
XOR_Password[31:0] = Password[31:0] XOR {Random_Number[15:0],
Random_Number[15:0]}.
To get out of the Privacy status, the valid Privacy password has to be transmitted to the IC
with the SET PASSWORD command.
The timing of the command is write alike.
8.4.3.11 INVENTORY PAGE READ
Command code = B0h
When receiving the INVENTORY PAGE READ request, the ICODE SLIX-S IC performs
the same as the anticollision sequence, with the difference that instead of the UID and the
DSFID, the requested memory content is re-transmitted from the ICODE SLIX-S IC.
If an error is detected, the ICODE SLIX-S IC remains silent.
If the Option flag is set to logic 0, n pages of data including page protection status
(password protection condition) are re-transmitted. If the Option flag is set to logic 1,
n pages (4 blocks = 16 byte) of data including page protection status (password protection
condition) and the part of the UID which is not part of the mask are re-transmitted.
The request contains:
• Flags
• INVENTORY PAGE READ command code
• IC manufacturer code
• AFI (if AFI flag set)

ICODE SLIX-S
• Mask length
• Mask value (if mask length > 0)
• First page number to be read
• Number of pages to be read
• CRC 16
The Inventory_flag must be set to logic 1.
The meaning of flags 5 to 8 is in accordance with table 5 in ISO/IEC 15693-3.
The number of pages in the request is one less than the number of pages that the ICODE
SLIX-S IC returns in its response.
If the Option flag in the request is set to logic 0, the response contains:
The ICODE SLIX-S IC reads the requested page(s) including page protection status and
sends back their value in the response. The mechanism and timing of the INVENTORY
PAGE READ command performs the same as the INVENTORY command which is
described in clause 8 of ISO/IEC 15693-3.
The requested page(s) is (are) transmitted in the following format and repeated as
necessary (depending on number of pages):
If the Option flag in the request is set to logic 1, the response contains:
The ICODE SLIX-S IC reads the requested page(s) including page protection status and
sends back their value in the response. Additionally the bytes of the UID, which are not
parts of the mask and the slot number in case of 16 slots, are returned. Instead of padding

with zeros up to the next byte boundary, the corresponding bits of the UID are returned.
The mechanism and timing of the INVENTORY PAGE READ command perform the same
as the INVENTORY command which is described in clause 8 of ISO/IEC 15693-3.
The requested page(s) is (are) transmitted in the following format and repeated as
necessary (depending on number of pages):
Remark: The number of bits of the re-transmitted UID can be calculated as follows:
• 16 slots: 60 bits (bit 64 to bit 5) - mask length rounded up to the next byte boundary
• 1 slot: 64 bits - mask length rounded up to the next byte boundary
Remark: If the sum of first page number and number of pages exceeds the total available
number of user pages, the number of transmitted pages is less than the requested
number of pages, which means that the last returned page is the highest available user
page, followed by the 16-bit CRC and the EOF.
• Example: mask length = 30 bits
• Returned: bit 64 to bit 5 (30 bits) = 30 bits gives 4 bytes
8.4.3.12 FAST INVENTORY PAGE READ
Command code = B1h
When receiving the FAST INVENTORY PAGE READ command the ICODE SLIX-S IC
behaves the same as the INVENTORY PAGE READ command with the following
exceptions:
The data rate in the direction ICODE SLIX-S 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 SLIX-S IC and the time between the
rising edge of the EOF from the interrogator to the ICODE SLIX-S IC remain unchanged
(stay the same as defined in ISO/IEC 15693-3).
In the ICODE SLIX-S IC to the interrogator direction, only the single subcarrier mode is
supported.
