Develop reliable and durable nonvolatile memory solution with FT24C08A and PIC32MZ2048EFM100

/*!
 * \file main.c
 * \brief Eeprom Click example
 *
 * # Description
 * This is a example which demonstrates the use of EEPROM Click board.
 *
 * The demo application is composed of two sections :
 *
 * ## Application Init 
 * Initializes peripherals and pins used by EEPROM Click.
 * Initializes SPI serial interface and puts a device to the initial state.
 *
 * ## Application Task
 * First page of memory block 1 will be written with data values starting from
 * 1 to 16. This memory page will be read by the user, to verify successfully
 * data writing. Data writing to memory will be protected upon memory writing,
 * and before memory reading.
