 * @file main.c
 * @brief Power MUX Click Example.
 *
 * # Description
 * This Click features power multiplexer that enables transition between two power supplies, 
 * each operating at 2.8V to 5.5V and delivering up to 2A current depending on the package.
 *
 * The demo application is composed of two sections :
 *
 * ## Application Init
 * Enables GPIO and starts write log.
 *
 * ## Application Task
 * Changes power inputs every 3 seconds and displays the currently set mode on the USB UART.
