Transponder addressing
Addressing
The data memories are addressed linearly from address 0000 (or the specified start
address) to the end address. The CM or reader automatically recognizes the size of the
memory on the transponder. If the end address on the transponder is exceeded, the user
receives an error message.
The next table shows the address space of the individual tag versions. The ADR_TAG and
LEN-DATA variables must be assigned parameters according to this address space.
