These conventions are used in the following table:

•

# = Active low

•

I = Digital input

•

O = Digital output

•

I/O = Bidirectional

•

IA = Analog input

•

OA = Analog output

•

IPU = Digital input with internal pull-up

•

IPD = Digital input with internal pull-down

•

OOD = Open-drain output

•

O3S = Tri-state output

•

I/OPD = Bidirectional with internal pull-down

•

B = Bias

•

Bus naming convention: Pin label followed by {Port #}
