Abbreviation
I = input.
O = output.
I/O = bidirectional.
I/O T = bidirectional or high impedance.
BK: pin has a bus keeper function that weakly retains the last level
driven on an I/O pin when it is switched from output to input.
PU: pin has a nominal 50 A internal pull-up connected.
PD: pin has a nominal 50 A internal pull-down connected.
P: pin has programmable input characteristics.
