EEPROM Sector Mode — When this bit is 0, each sector is split into two pages (4-byte mode). When this bit is
1, each sector is in a single page (8-byte mode).
0 Half of each EEPROM sector is in Page 0 and the other half is in Page 1.
1 Each sector is in a single page.
Security State Code — This 2-bit field determines the security state of the MCU as shown in
the MCU is secure, the contents of RAM, EEPROM and FLASH memory cannot be accessed by instructions
from any unsecured source including the background debug interface. SEC changes to 1:0 after successful
backdoor key entry or a successful blank check of FLASH. For more detailed information about security, refer to
Section 4.6.9,
EEPROM Page Select — This bit selects which EEPROM page is accessed in the memory map.
0 Page 0 is in foreground of memory map. Page 1 is in background and can not be accessed.
1 Page 1 is in foreground of memory map. Page 0 is in background and can not be accessed.
Enable Writing of Access Key — This bit enables writing of the backdoor comparison key. For more detailed
information about the backdoor key mechanism, refer to
0 Writes to 0xFFB0–0xFFB7 are interpreted as the start of a FLASH programming or erase command.
1 Writes to NVBACKKEY (0xFFB0–0xFFB7) are interpreted as comparison key writes.
