Pwr = 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
