Notes:
1. P = Power supply.
I = Input.
O = Output.
I/O = Bidirectional.
Gnd = Ground.
Ipu = Input w/internal pull-up.
Ipd = Input 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.
2. PU = Strap pin pull-up.
PD = Strap pull-down.
Otri = Output tristated.
