A stuff count error occurs if th received stuff count value does not match the value
calculated from the own stuff bit count. Only relevant for CAN FD signals in ISO
standard.

13.5.3.2 Triggering on CAN FD data
The "Identifier + Data" trigger type supports triggering on data bytes of specific value at
specific location in the data field of a frame. The "Data Pattern" field provides 8 data
bytes to define the data pattern. For data fields longer than 8 byte, you can define the
position where the specified pattern starts.
The following examples demonstrate how the data pattern and data position are
defined.
To set up the trigger
1. Set the basic trigger events:
a) Select the source: "Serial bus".
b) Select the serial bus.
c) Select the protocol: "CAN/CAN FD".
d) Select the trigger type: "Identifier + Data".
e) Select the standard:"CAN FD" or "Any".
2. In this example, the identifier does not matter. Set the "ID type = Any".
3. Define the data setup as described in the examples.
Example: Triggering on the second data byte
The CAN FD frame has 2 or more data bytes, where the value of the second data byte
should be E7.
●
Set "DLC ≥ 2".
●
Set the data pattern: "= XX E7".
