The data output control port bus (DOUT_WORDS) controls the number of words on the data output bus. It is an AXI4-Stream slave interface. The data output control port bus uses the s_axis_dout_words_aclk clock. Ports associated with the DOUT_WORDS interface are present if DOUT_Interface is set to Unconfigured, or DOUT_Interface is set to Pre-Configured and DOUT_Words_Configuration is set to Per_Block or Per_Transaction (that is, the interface is not Fixed).
