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
