Writing data (such as EPC or USER data) to recognized data carriers.
The TID cannot be modified.

1) Length of the "ID" field depends on the selected EPC format.
2) Start address and number of bytes refer only to the reading in the user area (U). EPC and TID are always transferred in
their full length. Values depend on the data carrier being used.
3) Any character can be allocated to reserved bytes, which are ignored in commands to the BIS U.
4) Placeholder for data block. The data is sent aligned to the right and the remaining characters filled with 0x00. Only the
right-aligned values from the programmed number of bytes are evaluated.
