Figure 3-14. EEPROM Address Low Register (EADDRLO)
In normal modes, all EADDRHI and EADDRLO bits read 0 and are not writable.
In special modes, all EADDRHI and EADDRLO bits are readable and writable except EADDRHI[7:2]
which are not writable and always read 0.
For sector erase, the MCU address bits AB[1:0] are ignored.
For mass erase, any address within the block is valid to start the command.
