•CODE SLI IC

3.4.3.2 Fast inventory read

Command Code = A1 hex

When receiving the fast inventory read command the I

•CODE SLI IC behaves the same as in the inventory

read command with the following exceptions:

The datarate in the direction I

•CODE SLI IC to the interrogator is twice as defined in ISO/IEC 15693-3

(depending on the datarate_flag 53 kbit/s (high datarate) or 13 kbit/s (low datarate)).

The datarate from the interrogator to the I

•CODE SLI IC and the time between the rising edge of the EOF

from the interrogator to the I

•CODE SLI IC remain unchanged (stay the same as defined in ISO/IEC 15693-

3).

In the direction I

•CODE SLI IC to the interrogator only the single subcarrier mode is supported.
