 * \brief ClockGen2 Click example
 * 
 * # Description
 * This application enables generation of square waved clock signal in range from 260 kHz to 66,6 MHz
 *
 * The demo application is composed of two sections :
 * 
 * ## Application Init 
 * Driver initialization.
 * 
 * ## Application Task  
 * Changes the prescaler and enables/disables the clock output.
