6.6.1.3 EEPROM Security

MCF8316D provides configurable read and write protection to EEPROM registers. The level of protection can be configured using EEPROM_LOCK_MODE as per following list,

  • 00b : EEPROM read and write are allowed without a passcode
  • 01b : EEPROM read and write need a valid passcode
  • 10b : EEPROM read needs a valid passcode; EEPROM write is locked permanently
  • 11b : EEPROM read and write are locked permanently

Passcode is a 15-bit field in the EEPROM denoted by EEPROM_LOCK_KEY in the DEVICE_CONFIG1 register. EEPROM_LOCK_KEY is write accessible (when EEPROM_LOCK_MODE is set to 00b or 01b) but not read accessible.

When passcode based read/write protection is enabled (EEPROM_LOCK_MODE set to 01b or 10b), user has to write the passcode set in EEPROM_LOCK_KEY to USER_EEPROM_KEY bitfield in 0xF8 register after every power-up/wake-up before sending the first EEPROM read/write transaction over I2C. One valid passcode write after power-up/wake-up is sufficient for all subsequent EEPROM read/write transactions as long as there is no power reset, sleep mode entry, digital reset or incorrect passcode write. If an invalid passcode is written, the subsequent EEPROM read/write transactions are rejected - MCF8316D does not respond to the read/write requests. The read/write protection is applicable to EEPROM as well as the corresponding shadow/RAM locations. The EEPROM_LOCK_MODE as well as the passcode are part of the EEPROM registers and hence same level of read/write protection applies to these bit fields as configured by EEPROM_LOCK_MODE.
