The EEPROM emulator allocates a region of the device’s built-in flash memory to act as EEPROM. Unlike “true” EEPROM, flash doesn’t suffer from write “wear” with each write to each individual address. Instead, the page suffers wear when it is filled. Each write will add more data to the page until it is full, causing a page erase.
Sorry, but I don’t understand this “page erase” thing.
For example: if I
EEPROM.write(6, 126); two thousand times ( or 9 trillion times), will that cause a page erase?
