The data input control bus (DIN_WORDS) controls the number of words on the data input bus (DIN). It is an AXI4-Stream slave interface. The data input control bus uses the s_axis_din_words_aclk clock. Ports associated with DIN_WORDS interface are present if DIN_Interface is set to Unconfigured, or DIN_Interface is set to Pre-Configured and DIN_Words_Configuration is set to Per_Block or Per_Transaction (that is, the interface is not Fixed).
