2.2 Register Set
The reader has several system registers used for customization purposes. These registers are
stored in its non-volatile EEPROM. The reader accepts changes to these settings only during the
start-up phase. [See Write EEPROM, page 68]
stored in its non-volatile EEPROM. The reader accepts changes to these settings only during the
start-up phase. [See Write EEPROM, page 68]
Some of the system registers are organized such that each of the 8 bits is an on-off selection for a
feature. These are referred to as Flags. [See Set Configuration Flags, page 54]
feature. These are referred to as Flags. [See Set Configuration Flags, page 54]
Clearing all RFU bits is recommended in order to guarantee compatibility with future releases.
In addition, direct changes to some of these system registers may be made at any time, with
immediate effect, but these changes are NOT stored in EEPROM and thus are lost when the reader
powers down. [See Set Configuration Flags, page 54 and Set Configuration Register page 56]
These ‘on-the-fly’ changes are mapped onto the EEPROM ‘registers’ or memory locations and do
not necessarily carry the same ‘register’ values.

The reader can store up to 32 authentication keys internally to login standard MIFARE cards. An
additional 32 keys can be stored for DESFire authentication. All keys are read only and cannot be
accessed through the interface lines.
