When configured in the RF busy mode, the RF WIP/BUSY pin is tied to 0 from the SOF that
starts the Reset to ready 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 AFI
On receiving the Write AFI request, the M24LR04E-R programs the 8-bit AFI value to its
memory. The Option_flag is supported.
During the RF write cycle W
otherwise, the M24LR04E-R may not write correctly the AFI value into the memory. The W
time is equal to t
