Event notification (application setting)
Event notification is a special application similar to the burst mode. An event notification is sent if
there are changes in the device configuration or device status, regardless of whether data are already
being sent by burst mode commands. The status included in the device status byte, the extended
device status byte and in command 48 can be used for event notification. It is possible to specify a
specific number of bits that will trigger event notification. Event notifications have a low priority,
but carry a time stamp in order to record the first time when notification was triggered. Up to 5
different event notifications can be defined in the
Event Notification 1
to
Event Notification 5
windows.
