    Using DMA with Control Register



      I am using Control Register to write data to GPIO. I have to send a array to GPIO continuously. Size of array is 1Kbyte. I want to use DMA for Data Transfer. How do I write control register address to DMA for this?


      I also need a DMA interrupt. I need to generate a clock signal after each transfer data of the DMA. If the DMA transfer size is 1024 Bytes, I need 1024 interrupt. Because I need to generate a clock signal after writing data to the GPIO.


      How can I do this with DMA?


      Thank You
