The General Purpose Input/Output Controller manages the I/O pins of the microcontroller. Each
I/O line may be dedicated as a general-purpose I/O or be assigned to a function of an embedded
peripheral. This assures effective optimization of the pins of a product.

In order to use this module, other parts of the system must be configured correctly, as described
below.
Each I/O line of the GPIO features:
Configurable pin-change, rising-edge or falling-edge interrupt on any I/O line
A glitch filter providing rejection of pulses shorter than one clock cycle
Input visibility and output control
Multiplexing of up to four peripheral functions per I/O line
Programmable internal pull-up resistor
