When configured in the RF busy mode, the RF WIP/BUSY pin is tied to 0 from the SOF that
starts the Get Multiple Block Security Status command to the end of the M24LR04E-R
response.
When configured in the RF write in progress mode, the RF WIP/BUSY pin remains in high-Z
state.
Write-sector Password
On receiving the Write-sector Password command, the M24LR04E-R uses the data
contained in the request to write the password and reports whether the operation was
successful in the response. The Option_flag is supported.
During the RF write cycle time, W
