M24LR64-R
26.18
Fast Inventory Initiated
Before receiving the Fast Inventory Initiated command, the M24LR64-R must have received
an Initiate or a Fast Initiate command in order to set the Initiate_ flag. If not, the M24LR64-R
does not answer to the Fast Inventory Initiated command.
On receiving the Fast Inventory Initiated request, the M24LR64-R runs the anticollision
sequence. The Inventory_flag must be set to 1. The meaning of flags 5 to 8 is shown in
Table 26: Request flags 5 to 8 when Bit 3 =
2.
The request contains:
●

●
The M24LR64-R does not generate any answer in case of error.
Table 87.
The Response contains:

Table 88.
During an Inventory process, if the VCD does not receive an RF M24LR64-R response, it
waits a time t
of the request EOF sent by the VCD.
