    (P)”. 7.3.1 Ethernet message flag (E) When the CC320 is used to trigger a camera, the image processing can either be triggered by the acquisition of an image or by an Ethernet message sent from the CC320. When a trigger is received it is assigned a unique tag number (an incrementing number from 0 to 255).

    If the FIFO flag is not set, then an output cannot be re-triggered until the previous pulse has completed. Others triggers in this time are ignored If the FIFO flag is set, then multiple triggers are stored in the CC320 and a pulse is generated for each trigger at the correct time.
