Description
Reserved
EEPROM protection byte
Reserved
The EEPROM module has hardware interlocks which protect data from accidental corruption. A protected
sector is located at the higher address end of the EEPROM array, just below address 0x0FFF. The protected
sector in the EEPROM array can be sized from 64 bytes to 512 bytes. In addition, the EPOPEN bit in the
EPROT register, described in Section 3.3.2.5, “EEPROM Protection Register (EPROT)”, can be set to
globally protect the entire EEPROM array.
Chip security is defined at the MCU level.
