 * \brief Rtc9 Click example
 * 
 * # Description
 * This example demonstrates the use of RTC 9 click board.
 *
 * The demo application is composed of two sections :
 * 
 * ## Application Init 
 * Initializes the driver, wakes up the module, and sets the time and date.
 * 
 * ## Application Task  
 * Reads the current time and date and displays the results on the USB UART each second.
