How to write data to internal EEPROM. Arduino due.
Step 1. Put internal EEPROM into the Cortex M3 chip (carefully!)
In all seriousness, the Due has no EEPROM at all. There is the possibility to store things in the FLASH memory but, since it gets totally erased every time you program the Due, this is not ideal. So, really, if you need EEPROM you've got to put it on a shield.
The 16U2 is also connected to the SAM3X hardware UART...." . Can this be used ?
Could you not use something like an SPI-interface magnetic FRAM?
