 * \brief PLL Click example
 * 
 * # Description
 * This app sets PLL signals.
 *
 * The demo application is composed of two sections :
 * 
 * ## Application Init 
 * Initializes device.
 * 
 * ## Application Task  
 * Every 2 seconds, the PLL increases the input clock from min (x2) to max (x8) level.
