PUBLIC

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 45.

SLI-S HC IC

8.1.3.12 Fast inventory page read

Command Code = B1h

When receiving the Fast Inventory Page Read command the

I•CODE SLI-S/I•CODE SLI-S HC IC behaves the same as in the Inventory Page Read

command with the following exceptions:

The data rate in the direction I•CODE SLI-S/I•CODE SLI-S HC IC to the interrogator is

twice as 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 I•CODE SLI-S/I•CODE SLI-S HC IC and the

time between the rising edge of the EOF from the interrogator to the

I•CODE SLI-S/I•CODE SLI-S HC IC remain unchanged (stay the same as defined in

ISO/IEC 15693-3).

In the direction I•CODE SLI-S/I•CODE SLI-S HC IC to the interrogator only the single

subcarrier mode is supported.
