The stop command can be disabled.
Note:
For correct stop-mode operation it is necessary that the field be switched off instantly.
Password Function
The password function is a separate protection mechanism to prevent a base station
from reading or manipulating the internal configuration and data blocks of the e5561
without knowing the password. Only a transition to the crypto mode is possible. If the
password function is active, the base station must first send the password to enable any
other operations.
During password mode, the e5561 monitors several fault and protection mechanism. If a
fault or a protection violation is detected, the e5561 enters ID mode.
Mode Transitions
If the e5561 is in ID mode and the base station transmits a write sequence by interrupt-
ing the RF field, the internal mode changes according to the received write sequence. If
an error has been detected or the password function has been enabled, the e5561
remains in ID mode.
A transition to and from all other modes (except the ID mode) is possible by sending the
corresponding write sequence. Once the ID mode is left, switching to another mode is
only possible by sending an uncorrect data sequence to the transponder.

This diagram provides only an overview. In reality, more transitions are possible.
