ICODE SLIX-L
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-L 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
Table 30. Page protection status byte
Page Protection Status byte Page data
00h: page is public (not protected with Read password) or the
valid Read password has been transmitted before
16 byte page data content
0Fh: page is protected with the Read password and the valid
Read password has not been transmitted before
no data
Table 31. Response format: Option flag logic 1
SOF Flags Rest of UID which is not part of
the mask and slot number
Data CRC16 EOF
- 8 bits 0 to 64 bit Page status & data 16 bits -
Multiple of 8 bits Repeated as needed
Table 32. Page protection status byte
Page Protection Status Byte Page data
00h: page is public (not protected with Read password) or the
valid Read password has been transmitted before
16 byte page data content
0Fh: page is protected with the Read password and the valid
Read password has not been transmitted before
no data
