3.3.4 Tag UID Register
Table 3.4
Tag UID Register is 10-bytes long, located at addresses from 0x0014 to 0x001D, with read only access. In most cases
the tag UIDs are 4 bytes, 7 bytes or 10 bytes long, thus this register can cover the longest UID but not necessarily all
bytes available in the register will be used. Bytes within the register are ordered from the least significant byte to the
most significant byte. This register is updated whenever Get UID and Type commands are used. The Tag UID Size
Register contains information detailing how many bytes of the ten available represent the tag UID.
