5.30 View Decoded Transactions
After you set Display Options, the Trace View screen is re-drawn to display decoded
transactions in the colors and format you selected.
When you instruct the Analyzer to display USB transactions, the components of each
transaction are collected from the current recording and are grouped and indented below
each decoded transaction. Each row shows a transaction with a unique numeration, a
label, and color-coded decoding of important data.
Note: If CRC errors are found in a DATAx (2.0) packet or a DP (3.0) packet, the data in
that packet will not be promoted to the Transaction, Transfer/, and so on, levels above,
since it is assumed that the data will be re-sent. The data count will show as 0 Bytes.
