Push Button Based SD/HD/3G SDI Evaluation
The EVK can be configured for evaluation by using the push buttons on the Cyclone III main board only. The
push button interface allows the EVK to be configured in the same modes as the terminal interface option.
However, only the Nios II terminal interface allows for device and FPGA register access.
