2. 8/6/4 available configurable IOs can be configured to any of the 10 IOs of the package. After any of the 8/6/4 IOs are chosen, the remaining 2/4/6 IOs of the package
3. Avoid using GP1[1] and GP1[2] for driving LEDs. These two pins have special functions during power-up which is used at factory. LEDs connected to these two pins
are not available for any functionality.
