The CFSR indicates the cause of a memory management fault, bus fault, or usage fault. See the
register summary in
The following subsections describe the subregisters that make up the CFSR:
The CFSR is byte accessible. You can access the CFSR or its subregisters as follows:
•
•
•
• access the complete CFSR with a word access to 0xE000ED28
• access the MMFSR with a byte access to 0xE000ED28
• access the MMFSR and BFSR with a halfword access to 0xE000ED28
• access the BFSR with a byte access to 0xE000ED29
• access the UFSR with a halfword access to 0xE000ED2A.
