C, SPI, USB, CAN, CAN FD, LIN, and FlexRay Bus Trigger Data Matching
Rolling window byte matching for I
2
C, SPI, USB, CAN, CAN FD, and FlexRay. To use a rolling window to
trigger on data, you dene the number of bytes to match. Then the oscilloscope uses a rolling window to nd any match
within a packet, with the window rolling one byte at a time.
For example, if the number of bytes is one, th e oscilloscope will attempt to match the rst byte, second byte, third, and so
on within the packet.
If the number of bytes is two, the oscilloscope will try to m atch any two consecutive bytes, such as one and two, two and
three, three and four, and so on. If the oscilloscope nds a m atch, it will trigger.
