SPRUIU1C July 2020 – February 2024 DRA821U , DRA821U-Q1
The TR is able to select up to 2 of 3 trigger sources for a given TR. The events can come from the dedicated local event on the UTC itself or from two assigned global events that come from the PSI-L interface on the UTC. The trigger counters are always enabled so that events can be received prior to the TR getting loaded. The trigger counters are only decremented when the trigger is active and the TR has scheduled the first transfer of the transaction.
