whether labels or security bytes overwritted

[hotdog]

I am using codewarrior development studio for HC(S)08 special editon(V3.1). as i know, some labels are defined at $FFF6,$FFF8,$FFFC , but the security bytes are purposed to be stored at locations $FFF6–$FFFD. i wonder whether the security bytes could be overwritted when the labels and security bytes are used.

Hi Hotdog,

These addresses are in the Vector table the security code is whatever the vectors need to be. If you are not using some of the vectors you can put something else in there. It is better to use a dummy ISR (or several) and point to it to scramble up your security code. This way if the interrupt is somehow triggered your code won't "blow up"
