Response parameter:

Response parameter:
Figure 68. Lock-sector 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 Lock-sector command to the end of the M24LR16E-R response.
When configured in the RF write in progress mode, the RF WIP/BUSY pin is tied to 0 for the
duration of the internal write cycle (from the end of a valid Lock sector command to the
beginning of the M24LR16E-R response).
Present-sector Password
On receiving the Present-sector Password command, the M24LR16E-R compares the
requested password with the data contained in the request and reports whether the
operation has been successful in the response. The Option_flag is supported.
