M24LR64E-R
26.18
When configured in the RF busy mode, the RF WIP/BUSY pin is tied to 0 from the SOF that
starts the Fast Read Single block command to the end of the M24LR64E-R response.
When configured in the RF write in progress mode, the RF WIP/BUSY pin remains in high-Z
state.
Fast Inventory Initiated
Before receiving the Fast Inventory Initiated command, the M24LR64E-R must have
received an Initiate or a Fast Initiate command in order to set the Initiate_ flag. If not, the
M24LR64E-R does not answer the Fast Inventory Initiated command.
The subcarrier_flag should be set to 0, otherwise the M24LR64E-R answers with an error
code.
On receiving the Fast Inventory Initiated request, the M24LR64E-R runs the anticollision
sequence. The Inventory_flag must be set to 1. The meaning of flags 5 to 8 is shown in
