 * @file main.c
 * @brief Watchdog Click Example.
 *
 * # Description
 * This is an example that demonstrates the use of the Watchdog click board.
 *
 * The demo application is composed of two sections :
 *
 * ## Application Init
 * Initialization driver enables - GPIO, configure the watchdog window,
 * enable watchdog, also write log.
 *
 * ## Application Task
 * In the first part of the example,
 * we send pulses in a valid time window (Correct Operation).
 * The second part of the example sends pulses outside the valid time window
 * and then the watchdog detects a fault condition, display "Fault",
 * performs the reset and turn on the LED ( WDT FLT ) on the Watchdog click board.
 * Results are being sent to the Usart Terminal where you can track their changes.
