Chapter 25 2 Kbyte EEPROM Module (S12XEETX2KV1)
The EADDRHI and EADDRLO registers are the EEPROM address registers.
All EABHI and EABLO bits read 0 and are not writable in normal modes.
All EABHI and EABLO bits are readable and writable in special modes.
The MCU address bit AB0 is not stored in the EADDR registers since the EEPROM block is not byte
addressable.
25.3.2.9
The EDATAHI and EDATALO registers are the EEPROM data registers.
All EDHI and EDLO bits read 0 and are not writable in normal modes.
