Hi Amey,

Please look at my answer here:

I would like to add two more specific points:

1. S12Z MCUs have implemented ECC on RAM and Flash (you cannot use cumulative write into Flash).

2. Double bit ECC error, illegal opcode and illegal address access will cause Machine exception interrupt.

I hope it helps you.

Have a great day,
RadekS
