Doc ID 15336 Rev 11

LRIS64K states

An LRIS64K can be in one of 4 states:

●

Power-off

●

Ready

●

Quiet

●

Selected

Transitions between these states are specified in Figure 38: LRIS64K state transition

diagram and Table 16: LRIS64K response depending on Request_flags.

15.1

Power-off state

The LRIS64K is in the Power-off state when it does not receive enough energy from the

VCD.

15.2

Ready state

The LRIS64K is in the Ready state when it receives enough energy from the VCD. When in

the Ready state, the LRIS64K answers any request where the Select_flag is not set.

15.3

Quiet state

When in the Quiet state, the LRIS64K answers any request except for Inventory requests

with the Address_flag set.

15.4

Selected state

In the Selected state, the LRIS64K answers any request in all modes (see Section 16:

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
