Figure 20. Comparison between the mask, slot number and UID
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.
Nb_slots_flags = 0 (16 slots), Slot Counter is 4 bits
Nb_slots_flags = 0
