Inventory Initiated
Before receiving the Inventory Initiated command, the LRIS2K must have received an
Initiate or a Fast Initiate command in order to set the Initiate_ flag. If not, the LRIS2K does
not answer to the Inventory Initiated command.
On receiving the Inventory Initiated request, the LRIS2K runs the anticollision sequence.
The Inventory_flag must be set to 1. The meaning of flags 5 to 8 is given in
Request_flags 5 to 8 when Bit 3 =
The request contains the:
