Dear All,

            I want to use  DMA Scatter/Gather function of MPC5444P,but some experiment phenomenon Confused me,the following is my DMA configurations information:

      

Problem phenomenon:when the major loop completed,the value of DMA_0.TCD[18].DLASTSGA.B.DLASTSGA was added to the DMA_0.TCD[18].DADDR.B.DADDR rather than  the contents of TCD_SG1[]  is loaded into the TCD register, then a DMA Destination Bus Error occurred.

 Can anyone tell me how can i do to make the contents of TCD_SG1[] be loaded into the TCD register ?
