Figure 61. Write AFI 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 Write AFI 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 AFI command to the
beginning of the M24LR16E-R response).
Lock AFI
On receiving the Lock AFI request, the M24LR16E-R locks the AFI value permanently. The
Option_flag is supported.
