• EEPROM security access levels
The user data are separated in 8 pages, whose access levels (L0 to L3) are defined thanks to 2 bits, stored in
the ‘Security Map Register’ of the EEPROM. A security procedure based on a password is required to
execute the unlocking. The password is stored in EEPROM #06.
