Now I am using MC9S12DJ128 in our equiptment.
But I have one problem.
The codes I have writed in MC9S12DJ128 flash memory is erased sometimes.
When the code is erased, I write the codes again and it works well.
I don't know why.
This do not happen so often.
But, you know, it can be a big trouble.
Please help me to solve this problem!
