The GPIO[0-3] modules are hereinafter referred to as GPIO module.
This section describes the GPIO external connections (environment).
The general-purpose interface combines four GPIO modules for a flexible, user-programmable, general-purpose input/output (I/O) controller. The general-purpose interface implements functions that are not implemented with the dedicated controllers in the device and require simple input and/or output software-controlled signals. The GPIO allows a variety of custom connections and expands the I/O capabilities of the system to the real world.
The general-purpose interface can physically connect the device to a keyboard matrix and peripheral integrated circuits (ICs).
