FD bits
For standard settings " CAN FD" and "Any", you can trigger on CAN FD-specific bits.
"FDF"
The bit determines whether a frame is CAN or CAN-FD. It corre-
sponds to the EDL bit (extended data length), which only exists in
CAN FD format. If you do not know if the signal is CAN or CAN FD,
you can use this bit to identify the format: FDF = 1 is CAN FD, and
FDF = 0 is CAN. Set "X" if the format is not relevant.
"BRS"
is the bit rate switch bit. Value 1 means that the bit rate switches from
the "Arbitration rate" to the faster "Data rate".
"ESI"
is the error state indicator. Set "X" if the bit is not relevant.

Data setup: DLC, NDB, Transfer, Condition, Data min, Data max
The data setup consists of the transfer direction, the number of bytes, the condition,
and one or two data patterns.
To trigger only on data, set the "ID type" of the identifier setup to "Any".
"Transfer"
CAN only:
Sets the byte order (endianness) of the data transfer. With "Big
endian", the data is analyzed and evaluated in the order of reception.
With "Little endian", the instrument reads the complete data, reverses
the byte order of the data, and compares it with the specified data
word.
