- ↑ 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.
- ↑ 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.
- ↑ Can change to PWM mode on the onboard regulator. This will lower efficiency of the regulator raising power consumption, but it reduces the audible noise heard on lower current consumption.
