M24LR64E-R
26.9
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 M24LR64E-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 M24LR64E-R response).
Lock AFI
On receiving the Lock AFI request, the M24LR64E-R locks the AFI value permanently. The
Option_flag is supported.
During the RF write cycle W
otherwise the M24LR64E-R may not lock correctly the AFI value in memory. The W
