"WebWe will create registers in the FPGA that will act as the storage element for the memory mapped IO interface. Lets start with LED register. The register will be 8 bit, read/write with the output ported directly to the LEDS. A reset is provided that sets the register to logical 0. We have provided you with the following example code to do this. " - Memory mapped interface
