Notes:

1. P = Power supply.

GND = ground

I = input

O = output

I/O = bi-directional

Ipu = input w/ internal pull-up

Ipd = input w/ internal pull-down

Opu = output w/ internal pull-up

Opd = output w/ internal pull-down

Ipd/O = input w/ internal pull-down during reset, output pin otherwise

Ipu/O = input w/ internal pull-up during reset, output pin otherwise
