Split Frames
Some frames - mostly STP (SATA) - can take a very long time on the bus. For SATA
frames it happens when Host and target go into long Hold periods while writing or reading
the data. In this case it is not viable for the analyzer to record the whole traffic sequence
as one frame, and the Split Frame approach is used. The long frame is broken into a
sequence of smaller frames, which are marked as Starting frame, zero or more Middle
frames and an Ending frame. This is highlighted in the Trace View like this:
A frame transmitted by SATA initiator is split into three frames.
