Response parameter:
●
When configured in the RF busy mode, the RF WIP/BUSY pin is tied to 0 from the SOF that
starts the Write Single Block 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 write single block command to the
beginning of the M24LR16E-R response).
