5.4.2. Sleep Mode.
It is recommended to use the Sleep mode when a seal is not in use
in order to conserve energy. In this mode, the seal enters an extreme
power-saving mode. To exit this mode, interrogate the seal using the
DataTerminal or use the Hard Wakeup via the DataReader.
When the seal is in Sleep mode no EVENTS will be recorded
until a new SET is performed.
As opposed to the Normal mode, Sleep mode is not an operative mode.
5.4.3. Alert Burst Mode.
The seal should report any detected TAMPER event. The report can
be in the STATUS register of a VERIFY cycle. This approach is good
as long as the system's VERIFY cycle time meets the required system
response time. In applications in which the System Cycle is very long
and the TAMPER event is reported with a long delay, it is possible to
use the Unsynchronized Alert Burst mode. This mode allows the
seal to transmit a burst with a tamper message without waiting for a
Reader Session.
5.4.4. Events Footprint Mode.
A command issued by a Reader may be registered as an event in the
Events Memory by the seal.
This mode should be configured at the Reader before issuing the
command. This mode is useful for tractability purposes. It is possible
to track a specific Reader that performed the command by registering
the Reader ID in the seal's Event Memory with each command.
