EEPROM Byte Erase Mode

The EEPROM Byte Erase (EEBER) mode allows each write to the memory array to erase the selected byte. An erased byte always reads back 0xFF, regardless of the value written to the EEPROM address.

When erasing the EEPROM, the CPU can continue running from the Flash. If the CPU starts an erase or write operation while the EEPROM is busy, the CPU will be halted until finishing the current operation.
