Addendum to MC68HC908QB8, rev. 3

This addendum introduces a change to this data sheet.

Chapter 17 Development Support, Section 17.3.2 Security

A security feature discourages unauthorized reading of FLASH locations while in monitor mode. The host

can bypass the security feature at monitor mode entry by sending eight security bytes that match the

bytes at locations $FFF6–$FFFD. Locations $FFF6–$FFFD contain user-defined data.

NOTE

Do not leave locations $FFF6–$FFFD blank. For security reasons, program

locations $FFF6–$FFFD even if they are not used for vectors.

security function denies monitor mode entry if five or more of the eight

security bytes are $00 (zero bytes).
