 * @brief Headphone AMP 3 Click Example.
 *
 * # Description
 * This library contains API for the Headphone AMP 3 click driver.
 * This demo application shows use of a Headphone AMP 3 click board™.
 *
 * The demo application is composed of two sections :
 *
 * ## Application Init
 * Initialization of GPIO module and log UART.
 * After driver initialization the app set default settings.
 *
 * ## Application Task
 * This example demonstrates the use of the Headphone AMP 3 click board™.
 * The app is enabling and disabling headphone output by changing ENA pin state every 10 seconds.
