USB2 Decode Trace Annotations

Like all trace annotations, USB2 Decode annotations are rectangular shadings used to highlight messages on
decoded waveforms for easy viewing.

Tip: Data packets (or messages) on properly decoded protocol signals can be viewed using Serial Decode Trace
Annotations
(on page 18), the Protocol Results Table (on page 19), and/or by Searching for Messages (on
page 21)
(Types and Subtypes). Using these tools together provides fast insight to your data. See Serial Decode
Trace Annotations
(on page 18) for more information.

Messages shown as annotations, table columns, and search types for most protocols are classified into Frames,
Errors, Unknown, or Grouped Primitives specific to the protocol. Sub Types then further classify each main
message type into more protocol-specific messages.
