R column (reset state)
- 0: input disabled
- 1: input enabled
- 2: input enabled, pull down
- 3: input enabled, pull up
Strapping pins:
- 0: high - boot from flash, low - enter boot loader mode
- 2: low when pin 0 is low
- 12: if high, boot fail
- 15: if low, boot messages are not printed
N column (special notes): R: RTC/Analog, I: Input Only
Colors: strapping, internal flash, input only
