Response parameter:
Figure 62. Lock AFI frame exchange between VCD and M24LR04E-R
When configured in the RF busy mode, the RF WIP/BUSY pin is tied to 0 from the SOF that
starts the Lock AFI command to the end of the M24LR04E-R response.
When configured in the RF write in progress mode, the RF WIP/BUSY pin is tied to 0 for the
entire duration of the internal write cycle (from the end of valid Lock AFI command to the
beginning of the M24LR04E-R response).
