Field
Function
name
Domain Indicates the domain from the 16 domains, D15-D0, is accessed when a data fault occurs.
Takes values 0-15. The reset value is 0.
Status Indicates type of fault generated. See Fault status and address on page 6-34 for full
details of Domain and FAR validity, and priorities:
b0000 = no function, reset value
b0001 = Alignment fault
b0010 = Instruction debug event fault
b0011 = Access Bit fault on Section
b0100 = Instruction cache maintenance operation fault
b0101 = Translation Section fault
b0110 = Access Bit fault on Page
b0111 = Translation Page fault
b1000 = Precise external abort
b1001 = Domain Section fault
b1010 = no function
b1011 = Domain Page fault
b1100 = External abort on translation, first level
b1101 = Permission Section fault
b1110 = External abort on translation, second level
b1111 = Permission Page fault.
