ICODE 3 (TagTamper)

8.5.3.19 STAY QUIET PERSISTENT

Command code = BCh

When receiving the STAY QUIET PERSISTENT command, the label IC enters the persistent quiet state and

does not send back a response.

Note: The STAY QUIET PERSISTENT command has the same behavior as the mandatory STAY QUIET

command. The only difference is at reset (power off). If the power off time exceeds the persistent time, the label

IC switches to the ready state,.

When in PERSISTENT QUIET state:

• The label IC does not process any request where the Inventory_flag is set, except:

– If the AFI_flag is set, or

– If the QUIET and PERSTENT QUIET flags in the extended mode of the (Fast) Inventory command are both

set.

• The label IC processes any EAS ALARM request, and any addressed or selected request.

The label IC exits the persistent quiet state when:

• Reset (power off) exceeds the persistent time.

• Receiving a SELECT request. The IC goes to the Selected state.

• Receiving a RESET TO READY request. The IC goes to the Ready state.

The STAY QUIET PERSISTENT command must be executed in addressed mode (Select_flag is set to 0 and

Address_flag is set to 1).
