  1. ↑ The pad name does not often correspond with the functionality of the IO we use, but can be used to reference the pad in the CPU manual.
  2. ↑ This does not contain all of the functions possible for a pin, but the common functions as they are used on our off the shelf basebords. Consult the i.MX6 CPU Reference manual for a complete list.
