3.3 Memory Map and Register Deï¬nition
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 deï¬ned in the Device Overview chapter and is reï¬ected in the INITEE register contents deï¬ned in the
INT block description chapter. Shown within the EEPROM array are: a protection/reserved ï¬eld and
user-deï¬ned EEPROM protected sectors. The 16-byte protection/reserved ï¬eld is located in the EEPROM
array from address 0x07F0 to 0x07FF. A description of this protection/reserved ï¬eld is given in Table 3-1.
