+Data
+----
+
+File data_transfer_start_snippet.sr was recorded in a live setup, and
+contains the start of a write command -- but does not complete it which
+is why the decoder won't annotate the operation.
+
+File data_transfer_complete_simulated.sr contains a complete CMD24 start
+as well as the communication of the R1 response, the data start token,
+the payload data, and the data response. This capture was created by a
+simulation.
