3.3.9 EADDR — EEPROM Address Registers
The EADDRHI and EADDRLO registers are the EEPROM address registers.
Figure 3-10 EEPROM Address High Register (EADDRHI)
Figure 3-11 EEPROM Address Low Register (EADDRLO)
All EABHI and EABLO bits read zero 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.
3.3.10 EDATA — EEPROM Data Registers
The EDATAHI and EDATALO registers are the EEPROM data registers.
