GPIO - General Purpose Input/Output
Description
General Purpose Input/Output (GPIO) API.
This module contains functions to control the GPIO peripheral of Silicon Labs 32-bit MCUs and SoCs. The GPIO peripheral is used for pin configuration and direct pin manipulation and sensing as well as routing for peripheral pin connections.
