Chapter 13: Fault exceptions and fault handling

Abstract

This chapter introduces the fault exceptions that are available in Arm Cortex-M23 and Cortex-M33 processors. It also describes how information can be extracted from the fault status registers and from the exception stack frame to assist in the debugging of faults. In addition, this chapter also explains “lockup” and what software improvements can be made to make the system more robust.
