Note:

1. P = Power supply

I = Input

O = Output

I/O = Bi-directional

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

PU = Strap pin pull-up

PD = Strap pull-down

Otri = Output tristated
