Trigger support
Protocol Trigger (bus trigger) starts the capture on a protocol-level event: a frame, an address or data pattern, an error, or a timing violation, rather than a raw signal edge.
The analyzers can trigger on the protocols listed below. A protocol that is not on this list has a Decode & settings page but no Trigger & settings page, and cannot currently be triggered on.
- How triggering works: Pre/Post/Delay trigger and Pass Count.
- Building conditions: Clause Trigger and Parallel Clause Trigger.
- Shared rules: Trigger settings reference covers channel assignment,
XXh/Xdon't-care values, and the field enable/disable convention.
