6.4 ISO 15693 commands - Examples
6.4.1 Inventory
flags [hex]:
0x02 = High data rate
0x04 = Inventory
0x10 = AFI value is set
0x20 = Single slot
afi [dec]:
AFI value if 0x10 set in the flags
bitlength [dec]:
Bit length of the subsequent UID mask. A maximum bit length of 60 is permitted for 16 slots; a bit length of 64 is
permitted for one slot. The length of the subsequent mask is derived from this parameter.
mask [hex]:
UID mask for the inventory command - 1 to 8 bytes. If the bit length is "0", then a byte ("00") must be transmitted.
