 * # Description
 * This example demonstrates the use of Clock Gen 6 click board which acts as 
 * an astable oscillator.
 *
 * The demo application is composed of two sections :
 *
 * ## Application Init
 * Initializes the driver and performs the click default configuration which sets the digital
 * potentiometer to max position and enables the clock output.
 *
 * ## Application Task
 * Changes the clock output frequency by changing the digital potentiometer position every second.
 * The potentiometer position value will be displayed on the USB UART.
