LRIS2K states

Doc ID 13888 Rev 9

39/98

LRIS2K states

An LRIS2K can be in one of 4 states:

●

Power-off

●

Ready

●

Quiet

●

Selected

Transitions between these states are specified in Figure 37: LRIS2K state transition diagram

and Table 15: LRIS2K response depending on Request_flags.

13.1

Power-off state

The LRIS2K is in the Power-off state when it does not receive enough energy from the VCD.

13.2

Ready state

The LRIS2K is in the Ready state when it receives enough energy from the VCD. When in

the Ready state, the LRIS2K answers any request where the Select_flag is not set.

13.3

Quiet state

When in the Quiet state, the LRIS2K answers any request except for Inventory requests with

the Address_flag set.

13.4

Selected state

In the Selected state, the LRIS2K answers any request in all modes (see Section 14:

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
