Hi every one. I am working on Instrument Cluster which uses MC9s12xhy128 and the firmware is created by codewarrior 5.1 IDE. i have enabled the WDT and i want to hold some variables (like pointer position of panels) if WDT resets the micro-controller. any suggestion?

You can divide RAM into segments and use NO_INIT on one of them in the linker file.

From CW5.x help search:
