What is the rate of data transfer by the DMA. Since DMA is independent of CPU it does not work at the rate of CPU might be higher. Any idea on what is the clock to DMAC?
The DMA is clocked by BUS_CLK, so you need to check in your design settings. But beware - there are other factors involved. So check the technical reference manual (PSoC5 architecture TRM) for more details.
