SL2 ICS53/SL2 ICS54

I•CODE SLI-S/I•CODE SLI-S HC

PUBLIC

The requested page(s) is (are) transmitted in the following format and repeated as

necessary (depending on number of pages):

Table 42.

Page protection status byte

Page Protection Status byte

Block 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

If the Option flag in the request is set to 1 the response contains:

Table 43.

Response format

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

The I•CODE SLI-S/I•CODE SLI-S HC 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 a 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 at 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):

Table 44.

Page protection status byte

Page Protection Status Byte

Block 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

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
