7.6 EEPROM
All devices have EEPROM for nonvolatile data storage. It is either addressable in a separate data space (default) or
memory mapped and accessed in normal data space. The EEPROM supports both byte and page access. Memory
mapped EEPROM allows highly efficient EEPROM reading and EEPROM buffer loading. When doing this, EEPROM is
accessible using load and store instructions. Memory mapped EEPROM will always start at hexadecimal address
0x1000.
