Transfer Done

0 = Indicates core is generating traffic when STREN is 1, else core is in idle mode

1 = Indicates traffic generation completed

This bit is set to 1 when the core is disabled by setting STREN to 0 and the current transfer is completed.

This bit resets to 0 either writing 1 to this bit or enabling the core with STREN.

0 STREN 0x0 R/W

Streaming Enable

0 = Disable traffic generation

1 = Enable traffic generation

  1. W1C – Write 1 to Clear (to clear register bit, you must write 1 to corresponding bits).
  2. During traffic generation if the core is forced to stop traffic (either by writing STREN to 0 or using core_ext_stop pin), the core completes the current transfer gracefully before stopping.
