I'm a bit confused how memory mapped I/O works on a Raspberry pi

225 Views Asked by At

In memory mapped io for the raspberry pi, does the cpu write to ram and doe the io device then read that section of ram the cpu wrote to using dma? I'm getting this impression by looking at the diagram from the BCM2835 ARM Peripherals guide. Can someone please clear up any misconceptions I have.
