NOTE:
1. [x] = default
2. After a reset, all multiplexed GPIOs on the core and resume wells are configured as their native function
rather than as a GPIO
3. A= Amber color LED, G= Green color LED
- Both off: USB disconnected, disable or not configured
- Amber Only: Error condition
- Green Only: Fully operational
- Amber Blinking, Green Off: Software attention
