When receiving the Select command:
●
●
The M24LR64-R answers an error code only if the UID is equal to its own UID. If not, no
response is generated. If an error occurs, the M24LR64-R remains in its current state.

if the UID is equal to its own UID, the M24LR64-R enters or stays in the Selected state
and sends a response.
if the UID does not match its own, the selected M24LR64-R returns to the Ready state
and does not send a response.
