CAN (Controller Area Network) is a serial communication protocol of the ISO
international standardization.
By using the CAN bus trigger, you can trigger on Start of Frame, Type of Frame,
Identifier, Data, ID & Data, End of Frame, Missing Ack, or Bit Stuffing Error.
You need to specify the signal source, trigger signal type, sample point, and signal
rate of the CAN signal.
In CAN bus trigger mode, the trigger setting information is displayed on bottom
