    SPIS Example ( DMA ) STA violation at 66 MHz MASTER CLK

    user_483670151

      Hi,

         

      I am playing with the SPIS example, created by Creator 3.3 for PSoC 5.

         

      It compile without problems at 24 MHz MASTER / BUS CLK

         

       

         

      If PLL is changed from 24 to 66 MHz ( to increase CPU speed ) STA M0019 warnings are reported.

         

      It looks like SPIS to DMA interrupt connection timing problem.

         

      Is there a way around this, and still have full CPU speed ?

         

       

         

      SPIM Example doesn't seem to have this problem ?

         

       

         

      Thanks
