33/86

LRI1K states

An LRI1K can be in one of 4 states:

●

Power-off

●

Ready

●

Quiet

●

Selected

Transitions between these states are specified in Figure 37: LRI1K state transition diagram

and Table 9: LRI1K response depending on request flags.

11.1

Power-off state

The LRI1K is in the Power-off state when it does not receive enough energy from the VCD.

11.2

Ready state

The LRI1K is in the Ready state when it receives enough energy from the VCD. When in the

Ready state, the LRI1K answers any request where the Select_flag is not set.

11.3

Quiet state

When in the Quiet state, the LRI1K answers any request except for Inventory requests with

the Address_flag set.

11.4

Selected state

In the Selected state, the LRI1K answers any request in all modes (see Section 12: Modes):

●

request in Select mode with the Select flag set

●

request in Addressed mode if the UID matches

●

request in Non-Addressed mode as it is the mode for general requests
