Thanks. I'd noted that it did not have the external DMA pins that the MPC8349EA has. However, I believe that I can live with that. We had used those pins for flow control with an FPGA configuration controller. However, I can do that with an interrupt if need be. Ira - could you please take a look at the DMA controller and see if you think it'll work for us. Cheers, Dave
