8.4. [0x81] Write Configuration
The configuration of the Reader can be changed by means of the Write Configuration command. In
order to do this, the configuration memory is written to with 14 bytes long blocks and addressed by
CFGn in the byte CFG-ADR. The description of parameters can be taken from Chapter
