5. Register Set

The reader has several system flags customizing its behavior. The flags are stored non-volatile in its
EEPROM. It is recommended to keep all bits labeled RFU at their default state to guarantee further
compatibility.
Please consider that if any register is written, the reader needs a reset so that the changes may take
effect.
