MC68HC908QC16 Data Sheet, Addendum 5/2012
Freescale Semiconductor 1
Addendum to MC68HC908QC16, rev. 5
This addendum introduces a change to this data sheet.
Chapter 18 Development Support, Section 18.3.2 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.

Do not leave locations $FFF6–$FFFD blank. For security reasons, program
locations $FFF6–$FFFD even if they are not used for vectors. An improved
security function denies monitor mode entry if five or more of the eight
security bytes are $00 (zero bytes).
