 * \file 
 * \brief Power Reset Click example
 * 
 * # Description
 * Reads PWR and RST pin states and performs a control of the timer counter depending on the pressed button.
 *
 * The demo application is composed of two sections :
 * 
 * ## Application Init 
 * Initializes device and logger module, prints Initialization done message.
 * 
 * ## Application Task  
 * Checks the states of the PWR and RST pins and logs every change.
