Figure 58. Read Multiple Block frame exchange between VCD and M24LR16E-R
When configured in the RF busy mode, the RF WIP/BUSY pin is tied to 0 from the SOF that
starts the Read Multiple Block command to the end of the M24LR16E-R response.
When configured in the RF write in progress mode, the RF WIP/BUSY pin remains in high-Z
state.

●
The M24LR16E-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 M24LR16E-R remains in its current state.

If the UID is equal to its own UID, the M24LR16E-R enters or stays in the Selected
state and sends a response.
If the UID does not match its own, the selected M24LR16E-R returns to the Ready
state and does not send a response.
