 * @brief EEPROM 9 Click example
 *
 * # Description
 * This is an example that demonstrates the use of the EEPROM 9 Click board.
 *
 * The demo application is composed of two sections :
 *
 * ## Application Init
 * Initializes the driver and USB UART logging, disables hold and write protection.
 *
 * ## Application Task
 * Writes a desired number of data bytes to the EEPROM 9 memory into a specified address, 
 * and verifies that it is written correctly by reading from the same memory location.
