  • To enable use of internal pullup resistors in CoolRunner-II CPLDs ensure the default pin type is float or pull-up
  • Keeper and pull-ups are mutually exclusive in a single design, and pull-ups will not work if the default pin type is set to keeper
  • Go to 'FIT' options and set the pin type, here you can also set other options like the IO voltage standard
