104 / 126 page  Commands codes M24LR64-R 104/126 Doc ID 15170 Rev 8 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 = 1. The data rate of the response is multiplied by 2. The request contains: ● the flags, ● the Inventory command code ● the AFI if the AFI flag is set ● the mask length ● the mask value ● the CRC The M24LR64-R does not generate any answer in case of error. The Response contains: ● the flags ● the Unique ID During an Inventory process, if the VCD does not receive an RF M24LR64-R response, it waits a time t3 before sending an EOF to switch to the next slot. t3 starts from the rising edge of the request EOF sent by the VCD. ● If the VCD sends a 100% modulated EOF, the minimum value of t3 is: t3min = 4384/fC (323.3µs) + tSOF ● If the VCD sends a 10% modulated EOF, the minimum value of t3 is: t3min = 4384/fC (323.3µs) + tNRT where: ● tSOF is the time required by the M24LR64-R to transmit an SOF to the VCD ● tNRT is the nominal response time of the M24LR64-R Table 87.
