The GPIO module controls the device's digital and analog I/O multiplexing, which uses shared pins to maximize application flexibility. The pins are named by the general-purpose I/O name (for example, GPIO0, GPIO25, GPIO58). These pins can be individually selected to operate as digital I/O (also called GPIO mode), or connected to one of several peripheral I/O signals. The input signals can be qualified to remove unwanted noise.
