Exception handling and single/double bit error

Introduction

This document provides an overview of SPC564Axx/SPC56ELxx exception handling with

main focus on different kinds of exception that the application code may face during the

runtime like single and double bit errors in memories, MPU protection violation, AIPS

access protection violation and others.

It starts with the simple overview of Machine check interrupt highlighting important things

from application perspective. To get detailed view and to implement low level machine

check interrupt handler, it is necessary to use Z4 Core User Manual which describes all the

details about the Core exception and interrupts.

The following part describes the reason of the exception, how to find it and what possibilities

exist to remove the fault.
