GPIO ports configuration in ST30 devices

INTRODUCTION
The General Purpose IO (GPIO) Ports of ST30 devices are programmable by software
in several modes: Input, Output, Alternate Function, Output open drain, Output push-
pull, Bidirectional weak push-pull and High impedance. It is possible to manage
Analog input as well.
This document describes best practice for GPIO ports configuration.
