Hi Ergo,
EEPROM on the LPC11E6X don't have the erase function, just have read and write function.
When you do the EEPROM operation, you don't need to erase it at first, you can write directly.
If you want to make all the EERPOM address to the same data, you just need to do the writing operation.
Wish it helps you!
If you still have question, please let me know!
Have a great day,
Jingjing
