A2.3.10 Event tracing and triggers

Instruction event packets can be inserted in the instruction trace stream on every cycle, but if events are traced continuously on every cycle the instruction FIFO is unable to drain and overflows.

When used with the optimized Cortex®‑M33 TPIU, ATB triggers must not be enabled, TRCEVENTCTL1R.ATB must be set to 0.
