Photo 5—This configuration (Dawg) is loaded at power-up. I eliminated the Global Resources and user module Parameter windows so you can get a better view of the graphical design windows. I named the CY8C27443 pins using a window in the PSoC Designer IDE. Using that same window, I can select the pin drive and enable or disable the pin’s interrupt. Clicking on the pin also allows the global in/out connection of the pin to be set (green vertical bus lines to PSoC I/O pins), and you can set the pin’s drive and interrupt status.
