 * @brief EEPROM 12 Click example
 *
 * # Description
 * This example demonstrates the use of EEPROM 12 Click board™.
 * The demo app writes specified data to the memory and reads it back.
 *
 * The demo application is composed of two sections :
 *
 * ## Application Init
 * The initialization of I2C module, log UART, and additional pins.
 *
 * ## Application Task
 * The demo application writes a desired number of bytes to the memory 
 * and then verifies if it is written correctly
 * by reading from the same memory location and displaying the memory content.
 * Results are being sent to the UART Terminal, where you can track their changes.
