I am using MC9s08Dv60 HCS08 Freescale microcontroller.
At cold temperatures(-40 degC ) and at Hot temperatures (85 degC) we are always facing different kind of problems.
Some times even no output at all and even we saw some part of flash its been completely overwritten by something(i.e Flash code corruption) and even reset happens.
Whther this corruption of Flash is because of noise or  something?
What may cause this corruption ?
