The encryption time is programmable in two options: The entire algorithm AUT64 is exe-
cuted 8 or 24 times. This feature can be set at block 0, bit 7.
Stop Mode
If several transponders enter the RF field of the base station one after the other (e.g., in
a manufactoring step), it might be useful to be able to set the transponder in a passive
state. In this case, the transponder may be collected one by one and disabled after
being read out. To avoid a communication conflict, the base station has to transmit a
special data sequence to the active transponder(s) forcing them to enter the stop mode.
During stop mode, the e5561 switches off the damping as long as the RF field is
applied. After a power-on reset, the e5561 enters the start-up and the ID mode again.
An other possibility to exit the stop mode is to send the software reset (see Figure 30).
This command results in a new initialization of the IC.

Password Function
The password function is a separate protection mechanism to prevent that a base sta-
tion from reading or manipulating the internal configuration and data blocks of the e5561
without knowing the password.
The password function may be used to prevent unauthorized programming or reading
via direct-access mode. If the password bit in block 9 of the EEPROM is set, only certain
operations are posible, i.e., reading the ID code in ID mode or authentication.
