3.3 Memory Map and Register Definition
This section describes the EETS2K memory map and registers.
3.3.1 Module Memory Map
Figure 3-2 shows the EETS2K memory map. Location of the EEPROM array in the MCU memory map
is defined in the Device Overview chapter and is reflected in the INITEE register contents defined in the
INT block description chapter. Shown within the EEPROM array are: a protection/reserved field and
user-defined EEPROM protected sectors. The 16-byte protection/reserved field is located in the EEPROM
array from address 0x07F0 to 0x07FF. A description of this protection/reserved field is given in Table 3-1.
