Figure 39. Principle of comparison between the mask, the slot number and the UID
The AFI field is present if the AFI_flag is set.
The pulse is generated according to the definition of the EOF in ISO/IEC 15693-2.
The first slot starts immediately after the reception of the request EOF. To switch to the next
slot, the VCD sends an EOF.
The following rules and restrictions apply:
●
●
Mask value received in the Inventory command
The Mask value less the padding 0s is loaded
into the Tag comparator
The Slot counter is calculated
The Slot counter is concatened to the Mask value
The concatenated result is compared with
the least significant bits of the Tag UID.
if no LRI2K answer is detected, the VCD may switch to the next slot by sending an EOF,
if one or more LRI2K answers are detected, the VCD waits until the complete frame
has been received before sending an EOF for switching to the next slot.
Nb_slots_flags = 0 (16 slots), Slot Counter is 4 bits
Nb_slots_flags = 0
