5.4. Notification Mode
The Notification Mode is an extended option of the Buffered Read Mode: queued Transponder
data and optionally Input / Status events are notified automatically and asynchronously to a host
with the
response protocol. The destination address and the notification
conditions can be set in
7.38. CFG83: Notification Channel, Part 2
configuration block. In general,
the notification channel can be used simultaneously with the host interface.
In difference to the Buffered Read Mode procedure, a notification is normally not acknowledged by
the host. Thus, the deletion of the transferred data with the
11.6. [0x32] Clear Data Buffer
com-
mand is not necessary. As an option, the acknowledgement can be enabled to synchronize the
notifications with the host to prevent notification overflow in the host application.
The notification message format depends on trigger settings in
for the read mode in
7.10. CFG11: Read Mode – Read Data
7.11. CFG12: Read Mode - Filter
as well as settings for the notification trigger in
7.37. CFG82: Notification Channel, Part 1
. The fol-
lowing table lists the message formats:
Notification Trigger: continuous or time-triggered
Input/Status Event
Data Event
Read Trigger disabled
Input/Status and Data Events are notified together in one or multiple messages.
The message format depends on settings in TR-DATA of CFG11.
Read Trigger enabled
Notification separately and immediately,
if in:
CFG11: IN flag in TR-DATA2 is set
and
CFG12: flag is set for input and/or sta-
tus to be observed
NOTE: One notification can contain
more than one input/status event, if
multiple events occur at the same time.
Notification shortly after notification of
input/status event.
The message format depends on set-
tings in TR-DATA of CFG11.
Notification Trigger: host-triggered
Input/Status Event
Data Event
Independent of Read Trigger
Input/Status and Data Events are notified together in one message. The notifica-
tion is activated by command [0x34] Force Notify Trigger.
The message format depends on settings in TR-DATA of CFG11.
