 * \brief Audio Xover Click example
 * 
 * # Description
 * This example demonstrates the use of the Audio Xover Click board. 
 * The Click is an analog active crossover solution for two-way loudspeakers. 
 * The primary purpose of the crossover circuit in a loudspeaker is to split 
 * an incoming audio signal into frequency bands that are passed to 
 * the speaker best suited.
 *
 * The demo application is composed of two sections :
 * 
 * ## Application Init 
 * This function initializes the driver and makes an initial log.
 * 
 * ## Application Task  
 * This function enables and disables the Click board every 10 seconds,
 * and logs an appropriate message on the USB UART.
 * 
 * @note
 * The hardware revision v100 of the Click board works only with MCUs that operates
 * at 5V operating voltage level.
