    SPIS component for TX Issues

    gr_isrc_1487646

      All:

         

      The attached project uses the SpiS component for TX only. The SpiClk is supplied from external input pin.

         

      The SpiSS is controlled using a control register.

         

      The block of data is just a buffer preloaed with data 0 thru 50.

         

      The OScope screens show that it takes the SpiS 16 SpiCLk to tranfer each bit.  Channel 1 is SpiClk, Ch3 is the data.

         

      I am attaching only two screen shots (Xfer of 0x01 and then 0x03).

         

      What am I doing wrong?

         

      Appreciate any insight into this issue.
